VRAY-BASED METHOD AND SYSTEM FOR RENDERING PBR MATERIALS

摘要

A VRAY-based method and system for rendering PBR materials. The method comprises: 1, model grouping and pretreatment: performing automatic grouping according to material information and surface area of models; 2, model lightening and UV unfolding: reducing the number of grids of the models by means of lightening process, and unfolding UV coordinates in the grouped models on a map; 3, PBR material baking: using Vary for baking to convert Vray materials into PBR materials, and outputting a related VrayBakeElement; 4, dual UV channel display: using dual UV channel display when the PBR materials are rendered; 5, material compression, comprising: model compression and material compression; 6, KSF description file, which is used for describing currently displayed model information; and 7, entering a PBR rendering system for real-time rendering. The described method can improve the speed of 3D real-time rendering and reduce the requirements on a device and an operating system.
