It turns out I had a lot of touch-up to do in gimp to get those texture maps cleaned up. The result is pretty good! Once normal maps and specular are applied it looks a little “too much” but that’s because you aren’t ment to use complete texture maps with normal maps.
For now, I am sitting between two chairs with materials, maybe someday I won’t have to think about getting it to look ok with and without normal mapping, but i guess conversion rate is pretty low for those features at the moment.
You can see the difference, without and with materials enabled, I’ll let you guess which.
