Hello,

I tried this bug on house actor (BP constructed with 50 static meshes) and basic cubes one by one too, in both ways i got same problem… Tried it manually with pressing Z and automatically with timeline too.

Hi Name,

This isn’t a bug with UE4, so I’ve moved it out of the Bug Reports section. This is just visibility/occlusion culling. For a better understanding, I would suggest taking a look at this video: v=6MhsdwTW3SQ

Thank you!

Hi, thanks you a lot!
I turned off occlusion culling because HZB not helped me enough but its solved completely.

Hi its me again.

I want to also note, that i found the best solution for me - using “full opaque” translucent material (it does not causes problems with occlusion culling probably because opaque translucent material is never fully opaque). This also save some performance because i dont need to turn off occlusion culling…
