ray traced shadows w/ strange artifacts

[SloaneFragment (Sloane Lysbeth)]

hi,

if i use ray traced shadows i get these odd splotches. it’s hard to explain.

here it is without ray tracing:

with ray tracing enabled:

im using a 4070rtx and these are my project settings:

i disabled ‘ray traced shadows’ as i don’t want every light to use ray tracing by default. i get the same problem if i enable it.

Hi, do those rock meshes use nanite? Cause as far as I know nanite does not support ray traced shadows and will use the fallback mesh instead, resulting in artifacts.

Yeah thats nanite artifacts. There are 2 possible solution other than disabling nanite or not using RT shadows.

r.RayTracing.Nanite.Mode 1

Or you can try and push it off the surface a bit by tweaking
r.RayTracing.Shadows.AvoidSelfIntersectionTraceDistance
