IBL from KTX file?

I’m just digging around into various texture compression threads and I noticed that it’s possible to create a KTX version of an HDR file and use it in Filament.


Is it possible to do this in Babylon? If not, is there a similar way to set up IBL using something other than a DDS?

Pinging @bghgary and @drigax, the glTF A-Team

We don’t currently support KTX for IBL. @sebavan Please correct me if I’m wrong here.

We have our own custom format with the .env extension. See here.

Eventually, we will probably support whatever the glTF working group ends up with, likely using KTX2.

Yup currently only supporting our own packed format based on RGBD and png.

Would he be able to utilize the compressed environment textures that can be generated in the sandbox?

Which would have a better compression factor?

Oh yes, @Alex_B, you should have a look at Use a HDR environment (for PBR) - Babylon.js Documentation

and more specifically: Use a HDR environment (for PBR) - Babylon.js Documentation

This would provide you with a nice fully featured ready to go env for babylon.
