Invalid geometric normal

[glorybound]

[11:39:08.790] Warning : Invalid geometric normal (0 0 0) for "Non-converted Unicode render instance name".

I have Googled and found posts, but no solutions. It keeps my slave render node from joining. What is the issue? Everything I read mentioned a proxy issue.

Could you send us the scene in which the error occurs so we can troubleshoot?

ZIpped up and I am uploading the Google Drive. I'll share the link when uploaded.

Please let me know when you grab it, so I can delete it.

I requested access.

I only left it up for a day. I'll have to upload it again. I'll send it to support.

another project and the same issue. I just sent the file to support.

My two-hour bucket renders are also now taking 5 hours. When I try to render with the GPU, it is a noisy and splotchy mess. I am assuming it has something to do with that normal warning.

The issue is displacement on my wall.rar - I am unsure how to fix it; it is just a wall with a displacement.

What I discovered immediately is that by disabling the UVW mapping the issue disappears.
I'm not sure why that is right now but it may be a pointer

[glorybound]

When I disable displacement it works too.

It seems the warning is caused by VRayDisplacementMod's Keep Continuity option, which applied on, by the looks of it, imported geometry seems to cause trouble. Most likely some continuity adjustments are creating invalid normals (which would explain why it does not appear without the UVW Map - since maybe the manipulated UVs resolve it). Indeed, the geometry is not closed and there are many overlapping faces. I'm sure fixing them will resolve the warning.

Yes, imported CAD, but hasn't been an issue in the past.

Yes, imported CAD, but hasn't been an issue in the past.

I presume it just has the right order of polygons, which with keeping continuity creates the invalid normal.
