I was digging around for some Iridescence shader support in PBRMaterial and wondering if there is something built in that adheres to the gltf spec. I saw this [image] Khronos releases new PBR material extensions for better 3D asset visual realism The new extensions enable material prop…

@Anupam_Das hi just checking in, have you seen that the 5.0 release now has iridescence support? :slight_smile:
