When I use the official tool to convert the PBR format file, I will directly download the PBR file again, without converting it to Env format file. How can I solve this problem

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 ?

I use the Chrome browser.
*.PBR → *.ENV
like this
I followed this video.
If you want to create an env file.
- Get a hdr file first.
- Drag a glb file to open scene. Then drag the hdr file in sandbox. You will see the environment change.
- 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.
Drag a glb file to open scene. Then drag the hdr file
I used the method you said to operate, but I can’t see the effect of the HDR file and can’t find the “Generate .env texture” button
IT looks like your hdr is broken or unsupported in babylon. could you share the file ?
I don’t think the file is loaded
I downloaded hdr file from this website.
All the hdr files I downloaded here are not available, so I can’t load them on Sandon
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.
