Skin Design Animation... Where Should I Start?

Hi,

I'm developing a video-game where the playable character has a skin design that changes during gameplay (like some video playing on his flesh, for example).

How can I do this with textures/materials?

Thanks in advance to anyone who can help.

 

Render something to a RenderTexture and then apply this as a texture to the character. (Should actually be in the "General Graphics" subforum, since this is not an image effect.)
