angles distort material

[vanderloo]

I'm trying to get my steel roll-up garage door to render acceptably in an angled camera view but it distorts.
How can I correct this?
It looks ok when rendered straight on. Could use a little depth if anyone can guide me there.
But when rendered at an angle as in the attachment mainshop1, it's very distorted.

That looks like moire to me.

It's called moire effect and could be solved by using a different AA filter (among other things): http://docs.chaosgroup.com/pages/vie...ndMoireEffects

Another quick fix is rendering to a higher resolution.

edit: Morne was faster

Thanks for the replies. For the benefit of anyone else having this problem-
I tried half a dozen different filters and filter sizes and nothing changed at all.
So I changed Antialiasing sampler type from adaptive subdivision to adaptive and the problem was solved.

I didn't think anybody used adaptive subdivision any more, it's only really there for legacy purposes to my understanding. The adaptive AA has long been the standard.

+1
Some people still use adaptive subdivision
For me however, ever since switching over do adaptive dmc, I'v never looked back and sometimes I even forget there's also fixed and adapative subdivison. Havent had a need for it in a long time
