I dont remember if i asked this question but does vray render an outline of sim box when it is inside another sim box, when sim boxes have same/ different resolutions ? . A large fire sim box has different grid size than flying propane sim box. Or this is octane’s fault for rendering overlapping sim boxes? Thank you
Hello,
Haven’t seen such artifacts before. Can you try comparing it to a V-Ray or scanline render?
Hi Svetlin,
unfortunately we do not have vray. And it looks like 3ds max standard renderer is so slow it did not even render. Attached is the scene of overlapping grids and this is the link Unique Download Link | WeTransfer to a large fire and small propane fire sims through wetransfer.com. Anyway you can render it and see if it renders ok. Otoy cannot solve it. Not sure if it is phoenix bug or their bug. Thank you !

Thanks for the scene! Got it and rendered it with V-Ray and Scanline and there don’t seem to be such artifacts. You could turn off ‘emit light’ or order to speed up the tests. I’m afraid it could be an Octane issue since we are explicitly taking care of overlapping containers when rendering natively with Scanline or V-Ray and this must be handled explicitly by the renderer. Does it happen with FumeFX volumes and Octane?
Here is the modified scene for scanline with light emission disabled:

It seems like an Octane bug or limitation.
Best regards,

Hi Thank you all for replying. I think octane does not support fume fx yet.
