Facets in render when using a high focal length Tweet

[jonathanhadley]

Has anyone had the same problem

I can render with the focal length at 35 OK, but soon as I up the focal length to 300 I get facets on every surface.

35 focal length and 300 focal length

How do I solve this?

Hi,

Is the scene-scale plausible/correct? In other words, is the asset at the same dimension as of IRL?

If not, it's ideally best to scale it properly, otherwise, the rendering kernel allows to adjust via the Ray Epsilon parameter. If it is even related to that, which is my early guess with the least information that has been shared.

elsksa, you are awesome.

Based on the minimal info I gave you, you nailed it. I just upped the ray epsilon to.1 and job done.

Thank you so much.

Great to hear, you are welcome.
It's a common case with often the same recurrent "solution".
