Procedural Marble Shader

Blender only. 100% node-basedMade with 2.92Works in cycles and in EEVEENo models included. The renders are a demonstration only.

Documentation;Works best with Object coordinates. You will get the best result this way as the patterns will continue over edges. Will still work with UV and generated coordinates as well.  DirectionsThe easiest way to append this to your scene is to copy (CTR+C) an object from the blend file and paste (CTR+P) to your scene. Which should bring along the material.
Use;Commercial use is permitted but this shall not be included in an asset pack, kit bash, or sold at any sort of asset/resource marketplace and must be embedded components in media such as a video game, movies, or similar products.
