This strange shadow appears at the border of light and dark at the corner of the geometry. I have watched many tutorials and have never seen this situation. I have adjusted a lot of parameters, but this problem has not been solved.
Hope to get your guidance.
Thank you all in advance.
This is called the “terminator problem”, it is ubiquitous in 3d rendering and the easiest solution is to just use more geometry
Anyway, thanks so much!
We can fix this using face normal. Even with low poly geometry we can adjust smoothness of the object. Try adjusting the face angles.
try r.RayTracing.NormalBias 100 . But it will takes another problem.
And it dosen’t works on path tracing. so only smooth can fix it.
