Free Skin Textures
Here are some of the skin textures created by me that I use for my monsters. I have reduced everything to 600px x 600px to save my bandwidth.
You can purchase high resolution skin textures here – only $2 for 10 high res seamless files.
I use them in ZBrush to spray on colour to build up realistic skins textures for SSS Shaders such as VRay FastSSS.
