I keep forgetting to post here regarding this, so better do it now before I forget again.
The *.mat file I submitted for the Greyhound was using TGA files for textures, so they all go flipped upside down. So I made a new *.mat file using DDS textures instead, however when I try to make a new *.mat file it seems to be converting them all to TGA when I export it.
Is this normal? Will the Textures still be flipped upside down because they're TGA, even though they're supposed to be DDS?
Here's a picture. You can see the files in the Mat are TGA, but on the right you can see I have a DDS file loaded for the material.
