Hello!
I’m having an issue where certain shadows (primarily shadows being cast by objects being hit by my directional lighting) look very noisy.
In the image below you can see that shadows being cast by the fence (via directional light) onto the ground look pretty ick. However, if you look at the shadows being cast by the grass in the foreground or the playermodel from point lights - there’s no noise problem.
Thanks (:
What Anti-aliasing method are you using? Soft shadows such as raytracing or Virtual Shadow Map SMRT rely on temporal anti aliasing techniques such as TSR to blend out noise over multiple frames. The reason the grass looks fine is that it’s shadows are sharp, due to being close to the caster.
I was using FXAA, however I just tried TAA and TSR and there’s a big improvement - Shadows are still a little bit fuzzy but nowhere near as bad as it is with FXAA.
Thank you!
