Here are a few quick slide of my special studies on crosshatch shadows for 3ds Max, in here I am trying to achieve a 2D feel look from using a 3D software, this sketchy looking map will be used when a character is in pain, mentally and physically to represent that stressness in the visuals. It is done by using the Ink'n Paint material and use a crosshatch PNG above. I saved it as a image-sequence because I wanted a jump on each frame so it looks like its hand drawn at each frame.
