I can't really say what's going on since I don't use GIMP. Maybe check out this thread: http://forums.steampowered.com/forums/showthread.php?p=34562686#post34562686

Thanks. Ill check it out

Unfortunately it wasnt of help. But Ill figure it out one way or another. Thanks anyways, and thank you for makeing your newest TF2 Modeling Tutorial. Its the only tutorial that actually helped me.

I just downloaded Gimp and got it to work using the thread I linked you. Here are the steps I did:

Open gimp > new image 512x512 > using the brush tool, I made a simple red circle in the middle (make sure you flatten your image if you have multiple layers) > I selected the red circle using the magic brush tool > In the layers window I right-clicked the layer and chose "Add Layer Mask..." and chose "Black" > your image should disappear > with the selection still in place, use the fill bucket to fill the portion of your icon with white > your icon should appear again > deselect everything by pressing ctrl+shift+a > in the layers window, right-click the layer and click "Apply Layer Mask" > finally export the .tga file.

Ok, first of all, thank you for doing all of this. Second of all, did you try use the import tool and selecting it? Because usually when I export it from Blender as a tga I get an error trying to load it from the import tool.

Give me one second to try. Exporting from blender may not give you the alpha channel.

I dont think it does. It still said that it didnt fit in the 512x328 area for me

It's working for me. Make sure to deselect the "RLE compression" option when exporting as a .tga from gimp.

Oh, ok. That might be the problem because I always had it selected

Yeah that was the problem. Thanks again for helping me. I couldnt find a solution anywhere.
