Another subject I touched on the old forums a while ago. I personally find car coloring an essential feature in any racing game, with full RGB selection support and color picker integration. Are there any plans for such a thing in SD, and should we hope?
I took part at implementing this in vDrift two years ago. My part was changing the car skins to use an alpha channel, so the body could be colored under them. That's the implementation I would suggest in SD as well. Seeing car textures use the png format, I would give all parts except the vinyls an alpha channel, and let the body be rendered behind them with a code-specified color. Skins would also contain the headlight / taillight textures, and all parts that should not be colored.
SD has many cars with complex skins, and I can't guarantee doing this for most of them (unless the skin sources exist in psd format). But still, is there anyone wiling to work on this, and can we hope for it happening? I could not imagine any car game complete without this, and hope it will eventually be possible (even if not so soon).
