Huge scaled objects rendering distorted

[atoyuser1]

Hi, I am getting very strange distortions on an object when I scale it to enormous sizes. Here is what it renders as at a standard scale:

Here is what happens when it's scaled about 1000%:

Any clues why?

I am using R23 with PR5 on a Mac running Catalina

Thanks

Increase Ray epsilon in Render Settings.

Increase Ray epsilon in Render Settings.

Great, that worked, thanks!
Changed fro 0.0001 to 0.001.

Are there any downsides to this?

As far as I'm aware raising this settings will prevent light from bouncing between very close surfaces. Since you're at such a large scale I would think the only result would be positive. I bet the documentation has a better explanation.

Thanks. I am zooming out from earth, so I imagine I might notice when I zoom back in. I shall experiment

I can confirm this absolutely has an effect when rendering a smaller object. Shame there isn't a way of keyframing the Ray Epsilon

What I'm having to do is render 2 versions and fade the Epsilon in Premiere

You can animate on the render
