I've got a file that needs to be TGA for technical reasons. In that file, I've got two boxes in the lower half, just right of center, that need transparency. One is for glass (upper, fully transparent) and one is for a "smoke" sun visor (lower, gray/transparent).
The texture already has an alpha layer. If I click "Remove Alpha Channel" then the transparent square goes white and the smoke square goes gray.
I export this to TGA, can open the TGA, it shows as transparent.
When I import the texture to Unreal, the "Has Alpha Channel" is
True, but the transparent block now shows as blue for some reason, and the smoke block turns solid black.
I can't seem to figure out why this is happening. The best I've been able to find online is to use a PNG instead, but again I can't do that for reasons beyond the scope of this question.
I've also seen advice to tick an "alpha channel" option on export, but I have no such option when I export the file. All I get are the options for compression or no compression, and where the origin of the file is.
If this isn't possible then I can try to work around it, but I'd really like some help understanding what I'm doing wrong. I'm hoping someone here has seen this issue before.
