sure.

I've also noticed some reflection errors with PhotonGI cache, see attached. Seems to only be a problem when viewed at a glancing angle to the surface. What parameter can be changed to improve this?

I thought this would be easy to test, so I removed the volume, cache processing time didn't change.

I am really liking luxcore more and more. Im starting to get some good renders now.

although other camera angles are takin considerably longer, see attached. You have to consider how slow is your CPU: the pre-process of the same scene will take less than 5 minutes on an AMD 3900x. Anyway, what do you mean with "camera angles" ? Other point of views ? Yes, other point of ...

How can I proceed without reducing the poly count? There is a parameter to increase the accepted difference (in degree) between normals in cache entries. By increasing the value, you can reduce the amount of entries required to cover small details and/or very jagged surfaces. Thank you. I set it to...

Okay, so i copied the fog material node from the fog cube and pasted it into the camera volume and selected it for the camera. Now I see the fog when I am inside the cube. Thank you. But why do I need the cube? I just deleted it and I still have fog visible... so I dont need the cube? Its a bit conf...

So I removed all the high poly columns and instances, this reduced the scene to 400k polys. I tried the PhotonGI indirect cache and it completed in a few minutes. So I guess theres something about the column the cache cals dont like. Is it simply the poly count? I havent set up materials yet, it's j...

I did see that option, but I dont understand what it is supposed to do. Im a Blender newb. I opened the volume node editor but it was unrelated to my fog cube object.

How should I set the camera "volume" option?
