HI,
here my second Visual generator. I guess i'm doing things right i can handel 60 fps on a 1650 in a laptop. This guy is made from 3 render. One is the shape, Torus + carve + double Twist is a really good solution for a snake-like shape. The texture is modify in sop world. Texture Sop is really powerful . Again here commercial use is disable. In the Post/color correction i'm using a shader from a guy. Please read the code to have more info about it. The rest of the patch is free for everybody. ( you can just make a blur-feedback instead of that shader will look more or less the same). Hope you like it .... :-)
