GlTF PBR (Content Creation)
From OpenSimulator
This page is part of the Content Creation section of the OpenSimulator wiki.
At the time this is written (May 2023) Linden Lab is working on a project to implement PBR like materials according to the glTF standard and it's likely Opensim will follow suit. There is not much information available at the moment though nor is there a set timeline for the development.
