Quote from: Matt on November 11, 2019, 04:32:32 pmThere are two problems here.With bump mapping it's partly due to this what were talking about recently: https://planetside.co.uk/forums/index.php/topic,27221.0.htmlI'm going to implement a solution to the bump issue soon.However, even without bump mapping there is the shadow terminator problem which you will see in lots of renderers:https://computergraphics.stackexchange.com/questions/4986/ray-tracing-shadows-the-shadow-line-artifacthttp://wiki.povray.org/content/Knowledgebase:The_Shadow_Line_ArtifactI don't have a solution yet but I'm going to take another look at it soon. There are some ideas for me to try in that stackexchange link.In the mean time, you'll need to heavily subdivide the object to the point where the polygons produce a visually smooth surface.
