[agracier]

I use only photoshop for my textures.
What's your problem exactly ?
hock: oups....Agracier you are too fast for me !

I don't think he means making textures, I think his problem is shifting RGB values for the texture areas on map_T.tga

For instance, he paints RGB 7 and RGB 31 and somehow when flattened (?) they turn into RGB 6 and RGB 30 ... giving wrong values of course and throwing off the textures used according to the load.ini.

I have a suspicion the problem lies in not using multiple layers in making map_t. Every RGB value should normally have a separate layer. UNLESS you paint in textures in the map-maker ... but that is whole different technique.
