Shading issue on large (scale ) objects

[yoscoob]

Hi all, I've been battling with an annoyance for a while and finally decided to reach out! When working with large objects (in the example below object has a height of circa 500m) I get this strange shading effect. I get it regardless of projection (UV, flat etc), polygon or primitive object. The Cube in mage 3 doesn't even have a material assigned to it. I've noticed it since Octane 4. Scaling the scene to make it smaller won't help in this instance as I need the scale for accurate TFD sims. Although that does clear the issue. Now I'm sure it's something I'm doing wrong! I just don't know what. Does anyone else experience (and hopefully address) this?

Thanks all!

Thanks Oktar, I knew there'd be something simple!
