Actually, you wouldn't need to recolor hundreds or thousands of textures to accomplish this. There are what, four, robots you can build? There are only four textures, total, for all the robots. I've looked into this already and found out that each robot has one diffuse texture for all of it's possible parts. It is also in grayscale so that other colors my be applied to them without actually recoloring the textures yourself. If anyone knew how to alter the grayscale to include more colors then I think it would be fairly easy.
Not exactly true. Im not sure about the robots in vanilla, this may be the case, but for the dlc there are about 80 texture files for the build-a-bot- robots. and all the material swaps are doing is remap the color. So to make custom textures could take a bit, i wont do too many, but im thinking faction themes, the trick will be getting the textures to be seamless accross all the different types of robots.
maybe a paintjob to represent each shop type, and maybe a few racing stripe type ones? idk let me know.
Some of the files just to name a few, but yeah, there are four robots you can build but tons of different armor upgrades, arm types, melee weapons, gun attachements, etc
P.S looking into the rust question.
Yeah, that's kinda what I was afraid of. I knew the single texture thing was too good to be true. You've got some good ideas, but more to the original point, how hard do you think it would be to make rust-less versions of the existing in-game paint jobs for custom Automatrons? I figure each armor piece would have to be individually colored. (Or recolored, as it were) I simply don't know if that entails painfully repainting each texture, or filling a texture with color and calling it a day. A modder I am not.
