Realtime Sub-Skin rendering
A new test using Screen Space Polygons : Sub-skin rendering.
For this demo i painted and animated the scarmap with a procedural noise, but since this map has a one to one correspondance with each surface of the 3d model, one could easily locate part of the character which has been injured and paint directly at that location, in the scarmap (it's just a one-bit map).
This technic is a convenient way to draw realistic wounds on monsters and bosses :-)
Ps: No animals were injured nor mistreated
