[ART] Slime textures

[JonnyAnomaly]

All the details that are not actual geometry were likely sculpted into a high polygon version of the monster, before being baked into a normal map. The shiny, slimy look to the flesh is probably achieved with a very bright specular map (to give it that "wetness") , which you can make from your diffuse texture.

The best way to get those lumps and awesome gross details is to first bring your character into a sculpting program, and sculpt away until you've got a a high detail mesh ready to be baked to your low poly mesh.
