I would really like to try putting the shadowmap resolution to a higher resolution (8k, 16k?) and/or increase the number of cascades. Is either of these possible?
I have a very large scene where you fly from the surface of a planet into space, and I cannot get the shadows to work in a remotely smooth or acceptable way.
If you want extremely high quality graphics, maybe look into HDRP. I think that can blend cascades and increase resolution above 4k.
In URP you probably need to adjust the render pipeline to fit your need, or make custom render features if you want to push limits.
Hi, you can increase the maximum shadowmap resolution after customizing URP package. ( refer to this )
Note: some low end devices don’t support 16K shadowmap rendering.
I think increasing cascade counts won’t be that easy because you need to change the shader code (shadowmap sampling) as well.
