The official tool should be the babylon sandbox. What browser are you using ? (only chrome/edge can be used so far to generate envs.) What file are you trying to convert ? ---

If you want to create an env file. 1. Get a hdr file first. 2. Drag a glb file to open scene. Then drag the hdr file in sandbox. You will see the environment change. 3. Open tools tab of inspector. you will see a button named “Generate .env texture”. ---

When I drag a hdr file into the sandbox, I can’t see any environmental changes, and the whole page doesn’t respond at all, but it happens when I drag a glb file. ---

I tested one. It should work. It’s best to provide your test file. ---

The file is too big to upload. 😭 Is it because the file is too big to load? I just downloaded a hdr file less than 2MB and can load it. ---

I only tested 4K.It worked. I don’t think it’s necessary to pursue too high resolution for create .env file. ---

I can not tell without the file unfortunately but going more than 2-4k has a huge chance to break depending on your hardware. ---
