You know, the issue where the shadows on low poly objects look like garbage and are distorted by the geometry despite smooth shading? [https://blenderartists.org/forum/attachment.php?attachmentid=298252&d=1395762708] Trying to do low poly stuff in cycles is a big “NO”. Just wondering if there is …

B.Y.O.B.: Made a post about that a while ago, not sure if entirely correct, but maybe it’s a bit useful: http://www.luxrender.net/forum/viewtopic.php?f=16&t=12915&p=122753 Even your ‘right’ example with the large arealight shows distinct squares of different shades on the sphere. Anyway, th…

Well, aren’t “subdivide moar” and using larger lights two sides of the same solution? The larger the terminator is compared to the faces, the less the issue will show. in any case, messing with the normals or baking normals and what not aren’t going to get you anywhere with this. The whole origin o…

If your light has shadow bias setting, use it, otherwise increase geometry. Left sphere rendered light shadow bias value 0, right sphere rendered light shadow bias value 0.002 (Vray 3) [image]

This topic is a little old, but I want to point out a simple solution for who wants to solve this problem on Cycles without increasing geometry, in material node editor, add input > Geometry node, add Color > MixRGB node, then set MixRgb note to subtract, connect “normal” of Geometry node to “color…

There is a righclickselect proposal : https://rightclickselect.com/p/rendering/Mtbbbc/fixing-terminator-effect-and-other-rendering-artifacts-in-cycles Upvote it ! [image] maraCZ: the main reason is that nobody actually knows how to solve it. Mental Ray and Mantra from Houdini which are ray…

That only fixes a narrow case where the problem wouldn’t be visible if it wasn’t for heavy bump mapping. The more general problem, where even simple smooth normals show the faceting, is not affected and is still with us.

Hmmm you might be right - I think I must’ve tested using the default sphere in eevee…:grimacing:

This has been bugging me off and on for a while now, but after playing around with adding the Subdivision Surface modifier, I found that if you set the Scene Render Engine Feature Set to Experimental, you gain access to the “Adaptive” checkbox in the Subdivision Surface modifier. Checking this box, …

By the way, I am using a Linux build from git master branch, version 2.82 from Oct 26, 2019.

Is there a workaround for the terminator problem?
