Why does bbl load 3D model using PBRMaterial? Can i change it to StandardMaterial on loading procress?
PBRMaterial is GLTF standard. If you use .babylon format it will be StandardMaterial (haven’t used .babylon format in a while, hopefully this didn’t change). Or you can load gltf, and create StandardMaterial manually and assign it to the loaded model.
GLTF file is more commonly used for 3D user, especially the supports by modeling softwares . I do not use .babylon format at present. But pbr has a higher performance cost, my projects always have numbers of mesh, it make scene can not get better optimization.
