Raytraced shadows dithering issue

[brume777]

Hey everyone,

I have this dithering noise effect at the edges of my raytraced shadows on any blank project with a simple direct light. Is this normal? Is there any way to remove/reduce this? See attached

Thanks!

Welcome to the Unreal Engine Forums! In regards to your noise problem in the shadows, is this the same issue you’re having? Issues with grainy shadows

that noise is kinda normal. it’s called penumbra. it’s emulating “contact hardening” shadows. or rather the other way around. you can change the size of the penumbra changing the source angle of the sun light. the noise is usually smoothed via tsr or taa or just setting the editor to realtime rendering.
