Cycles: Unintended Wave structure on cloth

Hello,

I want to render some cloth, which looks like this:

But as soon I zoom out too far Cycles generates some kind of wave structure on the cloth.

Any idea how to prevent this?

This is what you’re seeing:

Moiré patterns are commonly seen on television screens when a person is wearing a shirt or jacket of a particular weave or pattern, such as a houndstooth jacket… Because of this, newscasters and other professionals who regularly appear on TV are instructed to avoid clothing which could cause the effect.

thank you for that info! I think I just found a solution by myself. In my default settings I have a Pixel Filter of 1.0 instead of 1.5 (for sharper renders). If I change it back to 1.5 or switch from Blackman-Harris to Box, it’s fixed.
