Alpha Textures

[APproject]

Hello.

I try to rip these Feralas trees, coverted TGA into BLP, applied the texture and it has these rectangle textures with leaves beackground visible, I tried adjusting layers with Blend and Add Alpha, but all this led to a failure. Can anyone tell me how to deal with this so that only leaves are visible?

Thanks.

Model, BLPs and TGAs attached. This version is without further editing with transparent / alpha materials or texture IDs.

If it does not become transparent even if you set the material blending modes to transparent/blend then the texture probably lost its alpha channel.

^Attach the TGA and the BLP in a post here (or upload it to pastebin).

Attached to the first post.

That's odd. The TGA clearly have the alpha channels. I guess it's broken for the blp's, it's missing:/

Yeah, Talavaj was correct in that the BLP lost its alpha channel when it was converted.

In BLP lab, when you go to File -> Save As, click the "Alpha channel" button and make sure it is set to "Spec decides that for you".

In case you ever need to check whether an alpha channel is working, you can just click this button in BLP Lab (note: this is an image with a working alpha channel):

If it shows up transparent in the places it should be, then it should be working just fine. If shows up as all white, then it has an opaque alpha channel (where nothing is transparent), and that is usually a problem if the texture normally has transparency.

I also changed the model's materials back to transparent to test it out. It works ingame. Here it is fixed:

Thank you very much, you saved my skin once again, Purge. I am truly thankful for that.

This is why I just use TGAs. They're only slightly bigger and they're supported on so many programs. =\

From everything I do, it's very unlikely I'd ever reach that 8MB limit. So it's no problem for me.

EDIT: Oh, uh. This particular problem I have ran into before and I think it had to do with just the entirety of the actual texture file becoming corrupt for some odd reason. Try redownloading/re-exporting.
