I’ve been rendering with orthographic camera thus far, but have tried recently with perspective cam. I get this weird black, splotchy thing that doesn’t happen using orthographic. Any ideas how to get rid of it?
You got duplicate geometry.
Maybe you got a earlier version of the model or a ctrl+d copy in the file which you have hidden.
Or you simply got duplicate faces.
The z-buffer checking in perspective mode then is unable to determine which triangle is in front when they occupy the mathematical same space.
It might also be that the far limit of your camera is set too high, then this happens as well.
hth
Just changed far limit and no joy. There are no double vertices either. Any other ideas? Why doesn’t this happen with orthographic? The plane the figure is on is just a very simple cube (8 vertices). The black stuff is occuring there too at the back if you look.
OK. Deleted previous camera and using new one. It seems to be something to do with far limit and lens size. Thanks for your help.

“To the poor soul who did a search … say, three years hence … and “stumbled upon” your thread (“from three years ago…”) … and who was in the exact position that you once were … (believe it or not) …” what closing words might you now impart? What words might have saved you “hours of time” if you had but heard them timely?
To be honest I’m not exactly sure what the problem was but, like I said I deleted previous camera and set up a new one. However, with a lens size of about 50 I notice the black bits starting to appear again when the camera is placed far away from the figure. It may have been exacerbated before by some of the buttons I’d messed around with. This unfortunately is the best summary I can do.
