PBR BaseColor / Metallic Validate
In: Material Filters > PBR Utilities
Description
A utility node that generates a Good-to-Bad “Heatmap” on which values are correct or incorrect according to PBR standards.
It is very useful as a learning tool for PBR, since it provides very clear visual feedback of what the mistakes are and where they can be found.
Don’t use this as the end-all-tool, but still make sure you always have a clear understanding of why you’re breaking any rules this tool might highlight.
