Can someone tell me how ro save textures modified by the RealSkinShader?

You can't save the actual texture. realskin shader uses procedural nodes and mathmatics to create it's effect. the only possible method would be to apply the original skin texture to a flat plane, then use realskin on that plane, rendering it.

If you press the "+" at the bottom of the materials panel in the material room, you can save the texture with nodes, you then just double click to apply, like any other P5 material. However, as the real skin shader works out the nodes on the fly, depending on the light source and angle, your material which looks perfect in your current scene may look very wrong in your next one, with different lighting, POV, etc.

What are you using it for? You can extract it using the one sided square and the front camera.

Save it as a character ^karen1573^. you can save it in the materialroom too..2 parts..body and head. Just rerun the script for any new primary light you should choose, later.
