Im currenty working on a interior scene where create an interior from a floor plan, after its done loading I make a cube camera render of my scene and convert it to a equirectangular image.
When I add certain glb models the camera breaks with some sides being black and other not in the right place.

Same problem here with 157:
- EDIT 1 \* Problem got fixed for me after disabling “Y-UP” in Blenders GLTF Export and rotating the model in THREE.js instead.
- EDIT 2 \* There are still Problems when updating the cubeCamera with the rotated model, sometimes it works, sometimes not. ( cubeCamera is not updated every frame, only directly after loading the model,
Error-result is the same as shown in screenshots )
Render scene without .glb import : fine
Import the model, but dont add it to scene : fine
Add model to scene : cubeCamera breaks
After removing the model from scene and update cubeCamera : fine again.
Any Ideas what could cause the problem ? .glb is an export from blender

After tinkering with the scene a bit, when loading more complex models or a lot of them that’s when the camera broke. Maybe it could be due to WebGL limitations in the browser, but I can’t say for sure.
Disabling Y-up didn’t help in my case tho.

So in my case I ended up with removing the rotated model from scene and immediatly add it again before then updating the cubeCamera.
That somehow created a reliable result for me, I dont update the cubeCamera every frame tho.

After having that problem again with a different .glb file, I did some testing.
In my case the problem disappeared when I removed all opacity and transmission settings traversing the imported materials. When setting any material.opacity or material.transmission to anything different than 0, the problem appeared again…
Did test with an y-up exported model from blender only.
