[SOLVED] Changing alpha channels with GIMP?

[RNG_Wizard]

So, I've been messing around with GIMP to try and change textures on gloves, suits, and faces, etc, and the problem that I'm running into is that the textures are shiny once they're in game. I know this has to do with alphas, but after searching for hours I couldn't find a guide that tells me properly how to correct them. I DO have the dds addon, the only issue I have is that I can't figure out how to edit the alpha channel to resolve the whole shiny textures thing, I'm just new to everything here and clueless. If anyone could tell me how to correct alpha channels to remove the shine, maybe even provide screenshots or a video of how to fix the alpha channels, it'd be greatly appreciated. Thanks.

All I can say is really to read this guide. I am getting a similar issuse as well. There is a video of someone making a new retexture mod so, I'll put the link to the video here

I've read the guide word for word several times over now, but the problem I have with both of those is that they both go into detail on how to use Photoshop cs2, but not gimp, so neither of them are helpful to me.

Solved through trial and error. I thought the Alpha channel has to be entirely black as per https://steamcommunity.com/app/218620/discussions/15/1319962329027819455/

However, I needed to erase it completely. Issue solved.

Ah, you managed to figure it out. Like I said before, I am expercining a similar issue you encountered with GIMP so, maybe you can help me with it.

I'll take this step by step, and show you exactly what I did and how.

First off, open your "Channels" window. Windows > Dockable Dialogs > Channels

This window should be what opens up, the little one that shows your four channels. These control colors, and most importantly in our case, alphas.

Deselect the red, green, and blue channels, and go ahead and make them invsibile while you're at it. Be sure to specifically select and make the alpha channel visible, as seen here. The image you're editing should go pitch black, save for any transparent bits.

Using your toolbar, grab your eraser. Double click the eraser icon to open tool options, and make it massive.

Erase your alpha channel entirely.

You're done. Export the file as a .dds, since that's what gimp is capable of doing, rename it from .dds to .texture, drop it into the folder you need to get it working, and you're done. No more shine.
