Cube Skybox with PBR


Does PBR material work with a normal cube skybox ? As HDR file loading time for environment texture is quite horrible I am trying to avoid it and use a simple cube skybox for my environment. However I don’t know if my gltf models with pbr materials will work. Any suggestions ?

PBR needs IBL to be at its full potential :slight_smile:
We have a doc here explaining how to build a performant PBR compatible skybox: Use a HDR environment (for PBR) - Babylon.js Documentation

OK thanks. I suppose that the only way forward is to convert my hdr to dds using tools like IBL Baker. Loading time seems to improve with dds.

yup and once in dds, you can convert in .env as explained in the doc from @Deltakosh to minimize the transport time.
