Problems with changing scenes using .ply files

I have two different ply files, both in different scenes, which I can name “Garden” and “Floor 0”.

After starting the garden scene, I can switch to the floor 0 scene. When I switch, the background disappears from the garden scene after the transition. However, when I try to switch back from floor 0 to the garden scene, the transition works, the mesh file, characters, everything appears except the image file (ply file). How can I solve this problem?

You’d need to test this more to see what the problem is.
Are you saying that if you do not use ply files, switching works?
