Retera's Model Studio

[Retera]

I ask for help from experienced people.

The button Scripts > Convert HD->SD (experimental, baking) or whatever is a test button. The actual feature I was interested in was the "convert entire game" function on my computer. I added these options to convert a single model as a way to analyze how the code worked on a single model.

To generate this kind of conversion for all models in the entire game, it is possible to use the FtlopMaker:

FTLOP stands for For The Love Of Pete because you are probably making Pete Stilwell sad if you do this kind of thing. It's probably better to just use the original Frozen Throne graphics because they fit the game better.

Edit:

Can I ask why you are using MDLVIS? What is the point of doing that in this context?

I am glad to talk with the creator of this program. I see the Java code. But how to apply it? I don't quite understand what needs to be done.

I haven't quite figured it out yet, but as I understand it, MDLVIS is an unnecessary utility. All functions and manipulation can be done in "Retera".

 

[ALADEEN]

Right. I just feel you might be needing a lot of time to convert these assets when you could for instance use WoW ones or custom made better looking ones from the site.

Too bad that Asssssvi isn't active from some time. He's the best classic models creator around here.

 

[Retera]

I see the Java code. But how to apply it? I don't quite understand what needs to be done.

Retera Model Studio's full source code is available, meaning that a user can reconstruct their own version with their own changes.

If you load the code from the GitHub into a folder on your computer and recompile the program, Java allows us to launch specific "main" methods as their own programs from inside of any class. So the key is to launch the file I linked as a program.

Also, here were similar files to do the "texture bake" function on terrain and ubersplats:

The advantage of baking like this is that they might look better than if you simply convert the Diffuse directly, which would be missing normal/ORM information in the SD equivalent.

 

[Lt_Hawkeye]

trying to figure out why this model freezes the program when opened in mdl format, it is Vinz's ember model

 

[Retera]

mdl format

Here's your problem. Magos War3ModelEditor MDL format is not consistent with the Warcraft 3 game. My MDL loader was written to load MDLs saved by Blizzard's code. Loading an MDL in a different format is not supported.

I tried also the MDL format from the RMS program but that too freezes the program when trying to open it again in MDL format.

 

[aeman]

so this thing suddenly collapsing while im trying to install

edit: got through it, but its really complicated

 

[Retera]

that too freezes

Can you attach an example file I can use for bugfix testing?

 

[Lt_Hawkeye]

Here you go, this was converted directly from its original mdx using RMS.

As a side note, TRMS is able to open this model though with an error message.
Not sure if this error message could be useful but I am posting here as well.

 

[Retera]

As a side note, TRMS is able to open this model though with an error message.

Right, because TRMS uses the Warsmash MDL/MDX parser that I wrote in 2019, repurposes for a model editor

The DRMS version is using the parser I wrote in high school. It reads the model on the basis of a kid-like understanding that guesses and checks itself at each stage, assuming there might be parts of the MDL that it doesn't understand. It's so stupid. I'm not sure I want to fix this. The answer is TRMS and I don't have the time to replace the parser with my Warsmash one like Ghostwolf did when that project was getting started.

The bug is literally that it's like this giant rupe goldberg machine that reads the lines like a human and guesses what they might be, and it looks for Light on the line of text and if it sees that, then "it's probably a light emitter" and so it's invoking the Light Emitter parser on the ParticleEmitter2 "Light Tails" { line of this model.

That's so exceedingly dumb, it's like how if you open MalFurion and save as MDL then open it, DRMS can't open it, because the name of one of the MalFurion animations is not Stand but rather

Stand\n\n\n

with a ton of newlines after it, and this line-by-line feed guess and check system breaks on that.

I mean, literally in the time since when I wrote that, I went to college and got a degree that included courses in how to build parsers and I used all kinds of technologies to build parsers of all kinds, like how Warsmash parses JASS and FDF, and even then the Warsmash MDLX parser I figured was so brittle and so in need of being perfectly accurate that I literally just copied all of Ghostwolf's code from the hive "View in 3D" thing, basically 1 for 1 without changing it, because he was ahead of me. Rather than using the code like how I still use DRMS, he was literally rewriting the code over and over maybe in the hopes of getting the love and attention of other people. By comparison, his work is beautiful.

I don't have the time to do that, just don't name a freaking particle emitter "Light". Just name it BlizParticle0N where N is some number, and have a nice day.

Typically "at" is not the start of the error message. It appears that the entire error message was not included in your message, which makes it harder for folks like me to help you.

Can you paste the entire error message, as well as list what CASC settings you have in the data selection popup?

Thanks!I am attaching screenshots.I noticed that in the data selection window below there is a line "patch registry key", where the path to the old warcraft client is specified, not reforge, which I specified by mistake, and it does not change when I use the "add war3 install directory" button to specify the path to the normal war3 reforge client, there may be a problem in This?

 

[oGre2]

In general, I probably tried all the possible options, tried previous versions of the program, the same error

 

[SuperBRO]

Hello everybody! Well, it would be good if this program could be tagged with particle emitter and ribbon emitter.

 

[stan0033]

In the open file dialog, i cant paste text with ctrl+v or call the context menu to do so

 

[Lt_Hawkeye]

so I find a rendering bug with RMS.
At first, I was puzzled and thought I messed up somewhere in a very subtle way that was only caught in RMS.

How do I fix a program error?
"Retera Model Studio startup sequence has failed for two attempts. The program will now exit"

I think most people have encountered this kind of error while setting up the registry keys for using the RMS ("Path" Registry Key: Not Found error).
Also, please provide the full error log (or even the screenshot). I don't understand about this traditional error, since I don't use RMS a lot.

 

[StanMarsh8091]

Can someone help me with this? I am trying to export some textures but this is what tells me. I save the file as what the file type is, file type .TIF
But still says the same error.

 

[OrcMessiah123456]

@terrio I made some changes to the program's startup sequence, and a fix for a first-time launch crash. When you run it now, do you see any kind of error notification or anything else, or do you still have an issue where nothing happens?

Heya retera can I ask a question, so uh Im not using reforged, or the real warcraft 3, I used a crack version becuase I was freakin poor ;-;
Also I wanted to use ur studios, BUT The previewer doesn't let me show the models whatever Im trying to edit.

 

[Retera]

where the path to the old warcraft client is specified, not reforge, which I specified by mistake, and it does not change when I use the "add war3 install directory" button to specify the path to the normal war3 reforge client, there may be a problem in This?

No, I think there are two separate problems here. The "Path Registry Key" shown in Retera Model Studio does not matter. I left the key display there for users in case it helps them locate a legacy version of the game on their computer. It's a note for user information. The program does not actually use this setting. It only uses the settings you specify with the buttons.

Unfortunately, there is an issue in Retera Model Studio that seems to pop back up whenever I try to fix it. Basically, if you have Cyrillic alphabet installed on your computer, Java breaks and then the btnreplay-play.blp file path is changed to btnreplay <Cyrillic lowercase hyphen> play.blp which is a different string value and then it cannot resolve. Probably even if you change to the English version of Warcraft 3, you are still using the Cyrillic kind of Windows install and so it would still break. The way to fix this is a patch to Retera Model Studio itself. Maybe redownload the absolute latest 4.5 version and see if we fixed this in the code to process the Cyrillic alphabet.

a rendering bug with RMS.

Can you provide me the model file that has this issue? The code for how to render a Warcraft 3 model is not public. We only have the Ghostwolf remake, the Magos remake, the Mdlvis remake, and a few others. Nobody has the original code. So, that means that I cannot easily go and compare my code against some official source. Instead, if I am going to fix this bug, the easiest way is for me to look at an MDX file that renders different in Retera Model Studio than it does inside of Warcraft 3, at which point I can use that MDX file to identify where my node interpolation code is bugged. Especially if your model is missing start or end keyframes, it has been shown that Warcraft 3 behaviors are insane for those cases and matching the insane behaviors might be prohibitively time consuming. It's easier if you just fix the model. But I don't know if that is the case for your model or not without having the file.

while setting up the registry keys for using the RMS ("Path" Registry Key: Not Found error).

Again, the registry keys do not matter. What matters is the CASC or MPQ designation inside the popup Window.

Can someone help me with this? I am trying to export some textures but this is what tells me. I save the file as what the file type is, file type .TIF

That texture editor is weird and is due for a software upgrade. At the moment, it decides what image format to save the file based on the extension that you type thing.blp and not based on the dropdown option you choose (such as typing thing in the box and choosing BLP, which is the not working case).

The previewer doesn't let me show the models whatever Im trying to edit.

The problem here is most likely that your computer is crack like your Warcraft 3, and on the old computer it is probably failing to support the new OpenGL version that I had to use for rendering shiny Reforged model shaders.

When you have an old computer that can't do newer OpenGL like this, probably the easiest solution is going to be finding an older version of Retera Model Studio that was written against the older OpenGL version and does not use programmable shader code. It might be possible to use wayback machine to get an old Retera Model Studio, maybe something like 0.4.2. The old version would use the old render functions and then only require OpenGL 1.0 or OpenGL 2.0 or something.

This is just a guess, though. Maybe your problem is simpler to solve than that. I'm not sure without more error information.

"Retera Model Studio startup sequence has failed for two attempts. The program will now exit"

There was a problem in 4.4 and 4.5 it seems that caused this issue for some configurations. I just updated 4.5j with some code that might hopefully address the problem. (You need to redownload to get 4.5j because there is no automatic update system.)

It was with RMS I took my first step into a new world. I'm so greatful to You for make this possible

 

[Addplayerone]

Hello and sorry for interrupting, I am a novice user of RMS and have used this tool normally in the past few months.

My RMS version is V0.04.2 and im also use DemonReteraModelStudio 4.4.

Recently RMS has been prompting errors，after I re-install War3Reforged for about 2 weeks ago.

Other versions like 4.4m and 4.5j doesn't work eather.

I checked other people's similar questions，I guess it's caused by Warcraft updating?

Yes, you are correct. Older versions of RMS might not work if your Reforged is updated, and vice versa.

If you attempt to update the Reforged, it probably overwrites anything, including all of your custom data, without a warning, which means that you'll have to redownload and reconfigure the RMS from the scratch.

As a big reminder: the CASC file structure of the game has been revamped by the time Reforged released a patches (I think). This also prevents you for using the RMS on non-Reforged Warcraft III with CASC (1.30 and 1.31), due to those versions still using the old CASC format.

 

[Retera]

due to those versions still using the old CASC format.

But then, why is 4.5j not working for this user?

Maybe @Dr Super Good would know? It sounds like this is a JCASC issue.

Unless @Addplayerone if D:\Warcraft III on your computer is some old version of Reforged, and not the latest version?

Do not worry about "Path" key not found. That is a note at the bottom that might be helpful to some users, but it doesn't matter. The real problem is a JCASC parsing thing, where it is failing to parse the Warcraft III that you have provided.

This either means your Warcraft III is a different format than my Warcraft III, or else you are allowing Battle.net to do an upgrade while trying to run RMS at the same time, or some other similar problem.

 

[Dr Super Good]

I recall someone on discord running into pretty much the same error but the exact cause could not be found. My guess was a not-implemented checksum mismatch. The logic continues processing the data until another check, in this case checking the encoding key provided matches the encoding key guarding the file data, which throws the exception. I did implement the checksum check locally, but never pushed it to GIT.

JCASC does not support the BattleNet application modifying the local CASC storage while JCASC is trying to access it. If this happens you will likely need to restart the application, or at least instruct the application to reload the CASC archives. JCASC caches a lot of data about how data is stored in local storage, which becomes incorrect if the BattleNet application modifies the local CASC storage.

 

[Yy_yY]

where can I download older version, 0.04.4d for example?

 

[Retera]

download older version

I have not carefully maintained a binary backup record, but if you navigate to the GitHub and compile the program yourself it has a commit history of changes across versions that spans the past 8 years. You can use git checkout nameofcommit with some nameofcommit from any point during those 8 years to build and run the version from that point in time.

The old Matrix Eater has a great animation transfer tool that has become crucial to my workflow. Now these last few days, it just refused to function. Maybe it'll work out, but now I am really interested, since I am not sure from the description and discussion - does the new version also include easy animation transfers?

 

[oilio]

I have checked the latest version of Warcraft III, which is 1.36.1.21015. It seems that RMS cannot read the _hd.w3mod file of the latest version. I don't know if this is caused by the update to the latest version. However, when I switched to the previous version (1.36.1.20719), it became normal again. If users need to follow the latest version of Warcraft III, this is an issue that must be resolved.

 

[Dr Super Good]

Blizzard seems to have changed something with the local CASC storage format. JCASC is failing to process some files.


The following files cannot be processed by JCASC at the moment. RMS should not be trying to process these, but it could be an indication that other files might end up in a similar situation.

x86_64\clientsdk.dll
x86_64\world editor.exe
x86_64\warcraft iii.exe

 

[Retera]

does the new version also include easy animation transfers?

Yes. Retera Model Studio was designed to supercede Matrix Eater in every way. If you find that it is missing something, let me know and we can fix it.

Retera's Model studio isn't even running a first time start up for me. It just its not working, i copy pasted it into the warcraft III folder, and the warcraft III users/documents folder, nothing. Can i have some help? I don't know how to open this.

 

[Retera]

isn't even running a first time start up for me.

Another guy reported the same issue recently on Discord but I didn't hear back about whether he was able to gather additional debugging information. I don't know more about why you guys are experiencing this issue.

Have you ever run it previously on the PC in question? (I'm curious if there's some issue with a Retera Model Studio caching config, or if it's something new.)

Settings files are typically in C:\Users\<name>\AppData\Roaming\ReteraStudio and its safe to entirely delete them to make sure no UI stuff is getting kept from a previous version.

But, assuming you guys have never run the program on these computers before, maybe it's a different issue, such as a Windows version thing. I told the other guy to try running .\bin\drms.bat directly from CMD to see if there is any debugging output in the CMD window. I don't know if you know how to do that, but if you can figure it out, it might be a way to gather additional information.

 

[Player Warcraft Hive]

How do I fix it? In all versions I have this problem.

 

[Retera]

How do I fix it? In all versions I have this problem.

It seems that you have a good security setting that is not permitting Retera Model Studio to access the network adapters of your computer. That's a good security setting. Do not give access for Retera Model Studio to communicate with the network adapters of your computer; it does not need to do so.

The problem here may be due to the particular Java installation being used. In order to load an image file in Retera Model Studio (maybe the MPQ icon shown in the data wizard) the computer decided to access the network adapters. it seems that maybe the computer was using the network adapters to access information that the Java Standard Library believed would be "more random" than if it created information on its own. In general, I do not care the randomness of the file name of the MPQ icon and you should not care either.

If this problem persists, the best solution is to upgrade Retera Model Studio so that it does not touch the network adapters at all during the launch process, because Retera Model Studio is not a network application and should not need the internet for any purpose. There is no automatic update system, and so there is no reason for it to communicate with the network.

What can I download to fix this problem once and for all?

 

[Retera]

What can I download to fix this problem once and for all?

A different operating system than Windows XP.
The problem is that the Windows XP bindings of the network interface logic here:

jdk Cdiff src/windows/native/java/net/NetworkInterface_winXP.c

Is throwing an instance of java.lang.Error rather than an exception. But as we see here, in the code for the JDK17:

jdk17/src/java.base/share/classes/sun/security/provider/SeedGenerator.java at master · openjdk/jdk17

https://openjdk.org/projects/jdk/17 released 2021-09-14 - openjdk/jdk17

github.com

Currently the JDK17 has this kind of bug that when they use the local network interfaces as a kind of hack to get "random" information, they try to ignore any possible errors since the actual network is not needed. But they do not account for Error objects rather than Exception objects, and so you get this problem BUT ONLY ON WINDOWS XP probably.
If you must use Windows XP, then the solution is to use the source code of Retera Model Studio from here:

GitHub - Retera/ReterasModelStudio: Retera's Java WC3 libraries.

Retera's Java WC3 libraries. Contribute to Retera/ReterasModelStudio development by creating an account on GitHub.

github.com

The actual source code of Retera Model Studio does not include this bug that you are facing.
Rather, the problem is that I created the EXE download for Hive using a Windows 10 or Windows 11 computer and the result is that the tool includes a preset version of Java -- the Eclipse Temurin JDK 17 -- packaged in a way that targets Windows 10 or Windows 11 computers. When you use a computer that is older than this, it may be the case that the provided JDK17 binding is no longer the correct one.

So even though the code of Retera Model Studio does not need to change, in this case you want to change which Java install you are launching with so that you do not use the provided stuff in the download here on Hive Workshop. Instead, use some Java install that is specific to your system -- such as a Windows XP compatible JDK17 for you.

I don't know if Windows XP compatible JDK17 builds exist. It is possible that they do not exist. I live in the United States in the year 2024, but Windows XP reached its end of life for updates and support on April 8, 2014. As such, Windows XP has been an unsupported system for 10 years, and I do not know anyone who uses it. Therefore, I cannot further help you if you are on Windows XP because I have no equivalent machine to test with.

I run Retera Model Studio on many Linux versions, and if you run the source code, it runs fine on most of them.

I do

git clone https://github.com/Retera/ReterasModelStudio
cd ReteraModelStudio
chmod +x gradlew
./gradlew run

And this is usually enough to download and run Retera Model Studio on any Linux computer where Java 17 is installed. Maybe you will need to sudo apt install openjdk-17-jdk first before running the other commands that I listed above. Because I can freely install Linux on any computer, and run Retera Model Studio on that computer in 5 commands, my incentive to support Windows XP is quite low. However, I do have a sense of nostalgia that perhaps the computers were better 10+ years ago and that Warcraft III on Windows XP was a pleasant experience. So, in the end, I suppose that I wish you well even though you may struggle to solve this problem.
