Subsurf rendering problems in 2.28

Hi guys.

When rendering a mesh with subsurf activated a random number of black cells appear. It looks as if a mesh were superimposed to the subsurfed with its normals inverted, so you can see it here and there as a black wireframe.

It can be solved sometimes by increasing the level of subsurf or (obviously) by switching off the subsurf at all. (Or switching to 2.27 :wink: )

I've heard of other people at the hispanic community at nicodigital having the same problem, both linux and windows.

Any other suffering soul here ?

(I'll upload a screenshot soon).

Cheers.

Actually my last pic did that too, only my subsurf object had a white frame on it, it looked cool so I was only mildly annoyed at the time.

I'm experiencing the same thing. Upping the subsurf level by 1 seems to clear it up, but I'd rather not have to do that. What gives?

i belive its caused by face normals being different between two faces

therefore subsurf is soomthing thr colour between the wrong side of the faces.

i have never been able to overcome this issue really, its very annoying, i think that changing the face normals of the original mesh to face all the same way e.g. inwards/outwards then it should render fine.

mmmm I don't think so. It doesn't happen with 2.27 (and previous) (same file) plus it's a very simple model to have normal crazyness (a cube actually ! :D ).
