Yes, attach the example, please. I ll try to find the issue.

It’s very important to leave the objects you used in morph modifier in the scene when you export it to Verge3D.

Yiu have send two kinks to the app not the source files.

Try use no controls camera in the scene otherwise the camera controll will work instead of scrolling.

Yes, the only solution is to fallback to Blender 3.0.1

Use Animate Param puzzle instead of keyframe animation.

Unfortunally there’s not so much ways to effect the whole rendering picture, so better to setup all materials and lighting how it must be in the final result.

Yry to set delay between Replace texture and Play Video, I think the video just not loaded when you try to play it.
