Hi, we could isolate the problem in the RC_tiles002 object.
It seems caused by a bug in the Max boolean process, when processing this specific geometry.
Unfortunately this is not something we can fix it, but there is a simple workaround modifying slightly the object:
- Open Style Editor for RC_tiles002.
- Select A2S Generator and modify General->Clipping Area->Expand from 10% to 11%.
We are preparing a modified scene, with this fix applied.
