[LAL_RONE]

I think what LaRone was saying, was not make the dimension of the textures smaller..
He was referring to reducing the file size by four through indexing the color palette.
a TGA file in RGB color at 1024x1024 is about 4 MB
As far as I know the game doesn't read anything color wise above 256 colors.
So you are wasting a lot of memory.
If you INDEX the file down to 256 colors... keeping the dimension at 1024x1024
the resulting file size is only 1MB
I reduced several textures from the map to 256 colors and saw no loss in clarity.

YES !!!

All moders only should (when it is possible) use indexed TGA !!!!
A full of people find that MODS decrease FPS. It's important to do that. All my Hangar or fortification have better quality texture than Oleg's ones WITH a smallest size files.
