Haven’t been able to find anything yet on this little problem I’ve been experiencing. Seems I am getting holes in my model when vray renders it.
This model I imported from e-interiors. It looks fine in viewport and also when rendered with scanline but when vray interprets it, it decides to create all these gaps everywhere as if there were missing polygons ( though the gaps don’t actually conform to the size & shape of any existing polygons).
Originally the model had duplicate polygons (ie co-planar faces) and was rendering out with all sorts of weird moire patterns, so I painstakingly went through and deleted the duplicate polygons. The only thing that seems to help now is when I scale the model to say 1000% the holes seem to reduce. If i reduce the scale of it, the holes get worse. This is no solution because if I scale up the entire scene Max crashes when trying to render.
Has anyone experienced this before or know of a possible solution? It’s totally doing my head in! Thanks for any input you can offer.
Sounds like the scale is too small, how large is the scene in max units? If things get really tiny VRay will lose precision and starts doing things like this. It also happens if objects are located far away from the origin.
the scale is realworld units, in mm, same as every other project I’ve done.
materials are 2sided and the same thing happens with standard material or vray material.
actually…the holes arent even black…they are just holes. (ie.you can see through them). and as i mentioned the polygons appear fine since cleaning them up. The model looks fine to me… no co-planar faces and all adjacent vertices welded. Nice and clean. so what’s the problem??

I take it that is the display unit scale?
What is the system unit setup set to in this scene?
If display units are mm and system units are 1 max unit = 1 km for instance you could run into this issue.
I have converted to a 3ds file but i had to scale the crap out of it otherwise the exporting procedure screwed up the entire mesh. So when you import it, the model will be huge. Try reducing it to normal size and see what happens. The vertices will also need welding. This has got me totally baffled!
The original .3ds imported from e-interiors has over 18,000 errors in it! I can remove the open edges by selecting them in sub-object mode but that’s all.
Damn! Is there any way of cleaning it up that you guys know of?
