HummaWhite/LayerMatNode

Layered material shader node plugin for Arnold in Maya [2023]

LayerMatNode

Introduction

• LayerMatNode is a Maya Arnold plugin for rendering surfaces with layered material. With a few shader nodes you can easily create a range of surface appearances with texture-mappable parameters
• The BSDF model is derived from the paper Position-Free Monte Carlo Simulation for Arbitrary Layered BSDFs, Guo Yu et al. and promoted by PBRT as a standard. We further made it a usable tool
