Summary

If you AddEntities to a Scene and the client has Nanite Virtualized Geometry enabled, most entities disappear from the Scene. Their colliders still work. Objects using transluecent materials do not seem to disappear.

This seems new as of 37.20

Hi! Are these simple meshes and simple materials or is there a chance you have some complexity adding to this issue?

Is this all in editor or only in client? Is Nanite Virtualized Geometry the in client setting your are referring to?

Hey Kev! It appears to happen on a variety of material types for us, some are realatively simple and others are more complex triplanar setups. Materials that use translucency do not get this issue, but it does seem to univerally affect opaque materials for us in our current project.

The issue only happens on the client and only happens after an element is added to the scene. And yep Nanite Virtualized Geometry is the setting.

More than happy to share the project with you if that helps! Thanks.
