I'm trying to make a half decent Silent hill-esque texture for Sauerbraten.
The base texture works well and tiles seamlessly.
The only problem so far is the 'veins', which don't look much good when made tileable.
You might be able to get away with it though.
Free to use for personal projects. [Please credit me if you publish]
I'll post a fixed texture in this one's place if I manage to sort it out. = (^_^) =
