Nanite Build issue


I’d like to ask for some help.
I’m working on a sceen where i use some nanite Meshes.
The sceen is kind of done.
When i build it, it looks good on my PC, but when i start it on another computer with the same specs, the nanite meshes look strange. its like if the LOD is realy low.

Some pictures for about my problem.

Thanks for the help
