PBR-related Settings in Character Creator 2.0 Beta - Part 1
Interface of Texture Settings
One immediate noticeable difference in Character Creator 2.0 Beta is the addition of the Shader Type selection under Texture Settings.
- Classic Shader: Traditional texture mode same as iClone 6 with the addition of a new Ambient Occlusion channel.
* In the official version, the name of this shader is changed to "Traditional Shader". - PBR Shader: This mode will convert Specular and Reflection maps to PBR Metallic and Roughness equivalents.
PBR SystemMetallic and Roughness channels are the most important for the PBR system.
Various software approach PBR in slightly different ways, for more details take a look at
5 - PBR Visual Comparison
- Metallic: a greyscale map to determine the metallic and dielectric parts of the model.
- White is pure metal capable of reflecting the colors of the surrounding environment.
- Black is dielectric or non-metallic surface that can only reflect back greyscale highlights depending on the roughness of the surface.
- Roughness: a greyscale map to determine the microsurface qualities.
- White is a surface that is very rough and not at all glossy creating a very diffused look.
- Black is a surface that is very glossy and highly reflectant of the surrounding light sources.
You can get a pretty good feel of the system by simply filling a pure white Base Color then using Adjust Color parameters to tweak the Roughness texture.
