NGons in 3.0 not rendering consistantly

[3dreamstudios]

I know I read that NGons in 3x are supported, and in my experience so far they do render fine it seems. Until I began a sequence last night. Many frames had wierd issues with polys rendering correctly.

I will do another test but has anyone else seen animation sequences not render correctly when they have more than 4 sides? I was really hoping for this feature to work great, as I hate my models to be trippled...so hard to edit later.

The same object, without bones or other kind of deformations?

There is a new tool in the Octane custom object plugin to select the triangulation algorithm. Perhaps in your object, the "ear clipping" algorithm could work better.

Yea I need to install the very latest, I did read this was available. But have not had the chance to install and test. Will take a look. Thanks!

Ok, but anyway it is weird that the ngons tessellation is not same in all the frames if the object doesn't have deformations.

Yea I will do some more simple tests and see if I can nail down something that is repeatable. First time I saw it so far.
Yes not deformations etc...just simple room with ngons.

Can be perhaps a ray epsilon issue and not a tessellation problem? If you have a scene to reproduce this problem, please let me know.

I don't think this one is that....as when I trippled everything we are all good once again. When I get time (maybe this afternoon) I'll see if I can get a simple scene that can reproduce the issue I saw. Thanks.

...and you are realy shure that your surface smoothness number is correct for the CAD Files? is the geometry points from your object merged or unwelded/unmerged?

Yea the only thing I changed was trippling the geometry. However I am not able to replicate the issue with other ngons I've created. So....it may have been a combination of other things, who knows at this point. They were not Non-Planar, I do know that. but there may have been some non-planar polys in the scene at the time....hmm. I'll post again if I can replicate!
