Light/Shadow problem

How to get rid of this polygonal light/shadow issue? What is the best way?

from what i know you have to increase geometry subdivision, try a mesh smooth or turbo smooth on this object.

hope that helps.

Yes, unfortunately right now this is the only solution: https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180
But there is a chance that this will be fixed in 1.6.

Got it, thanks!
