BLP.NET CL

Very useful, thank you

whats BLP0?

whats BLP0?

It is a version of BLP that is used in Reign of Chaos (ROC) Beta.

I'm not very familiar with it but it is heavily discussed in this post. In summary, the difference between BLP0 and BLP1 is how mipmaps are handled.

I never encountered a use-case dealing with BLP0 in my projects. If it becomes a demand in the future, I can try to find a way to decode (and hopefully encode) it in BLP.NET CL.

Can this tool batch optimize a folder containing .blp files to .blp with lets say, 75% quality?

On an unrelated note on the tool, do you know of a way to separate mdx/blp files from other bloat/unused mdx/blp files? I have a list of mdx files my map uses, I just need to delete all other mdx files that isn't in this list, but then I have to check associated textures too, but this is very time consuming since theres over hundreds of models, got any ideas?

BLP.NET CL doesn't necessarily have batch operations but you can achieve it by executing the tool multiple times within a script file.

Assuming your operating system is Windows, create a .bat file inside the target folder and write the following batch script in your favorite text editor:

@echo off

rem Replace "%appdata%\BLP.NET\bin" where your blpnetcl is located
set blpnetclpath=%appdata%\BLP.NET\bin

set path=%path%;%blpnetclpath%

for %%f in (*.blp) do (
    if "%%~xf"==".blp" blpnetcl %%f %%~nf.blp -q 75
)

Once you save the .bat file, try running it. It should turn all the blp files inside the folder with 75% quality.

That is a very specific case. The one I found in Hive is this tool but I noticed you had issues with it.

You could try this simple program I made that does the same thing. If you still have problem with this, you can freely PM me.

Omg, absolutely amazing. The bat file works and the simple program as well. Blp to 75% quality works, almost no quality loss (can't see any to be fair). Map size reduced quite well, overall this was an amazing discovery, thanks for your amazing contribution Glint.

edit: Btw, I don't think this bat file can parse files with spaces in them?it seem to treat "myTexture hello.blp" as "myTexture"

edit2: Had ChatGPT revise it a bit, for anyone curious, this is what I'm using at the moment

@echo off
setlocal enabledelayedexpansion

rem Get the total number of .blp files
set count=0
for %%f in (blp\*.blp) do (
    set /a count+=1
)

rem Process each file and display progress
set processed=0
echo ====================================================
echo              Processing BLP Files
echo ====================================================
for %%f in (blp\*.blp) do (
    set /a processed+=1
    echo [File %%~nf.blp] Processing file !processed! of %count% ...
    if "%%~xf"==".blp" blpnetcl "%%f" "%%~nf.blp" -q 50
)
echo ====================================================
echo                    Process Complete
echo ====================================================

endlocal
pause

I think there might be something wrong with the program? I used 65% quality, and a lot of textures are bugged, like they look somewhat like this (on multiple characters)

Is okay if you provide me a sample of a bugged texture? It can help me to found the root cause of this issue.

Here is one of the models that was affected

PS. I noticed for the texture, I had a duplicate but with .tga extension instead, I deleted it now, but do you think that could be the cause? Although I had several models affected by this, so I don't know.

Eg.
myTexture.blp
I also had:
myTexture.tga
(forgot to remove these tga files)

I remember a friend of mine have this issue when we have both BLP and TGA textures with the same filename in our map. The solution I did was to remove the TGA copy.

Also, I found out another reason why the model is not shown properly: BLP.NET CL (as of 0.1.1) default mipmap value is set to 0. You could quickly fix this by adding the -m 15 option.

Example: blpnetcl a.blp a.blp -q 75 -m 15

You could lower the mipmap value as low as 1 to get a 30.33% file size reduction. Lowering the mipmap count may crash players who are running your map on a Mac. (Reference)

Your batch file should look like this with the fix:

@echo off
setlocal enabledelayedexpansion

rem Get the total number of .blp files
set count=0
for %%f in (blp\*.blp) do (
    set /a count+=1
)

rem Process each file and display progress
set processed=0
echo ====================================================
echo              Processing BLP Files
echo ====================================================
for %%f in (blp\*.blp) do (
    set /a processed+=1
    echo [File %%~nf.blp] Processing file !processed! of %count% ...
    if "%%~xf"==".blp" blpnetcl "%%f" "%%~nf.blp" -q 50 -m 15
)
echo ====================================================
echo                    Process Complete
echo ====================================================

endlocal
pause

Thanks for your help on this one. Once I push an update, the default mipmap value should now be 15.

It works now, flawlessly!

Approved! A useful command line tool for file format conversion with a lot of configurability. It is a bit slow though for BLP conversion but so is BLP Lab and this is using that internally.
