@slimbuck Thanks! I think the display of the sample has been improved.
I’m trying out Cubemap and IBL samples with some libraries in gltf-test.
If possible, I would like to make Cubemap/IBL samples as recommended by each library.
PlayCanvas Viewer seems to use HDR file for Cubemap/IBL, so I would like to use it, but I don’t know how to do it. I would appreciate any advice on how to use HDR files.
