I have been noticing this since the early Alpha, but it seems like with point lights, there are artifacts with shape radius anything above zero, if shadows are on. The higher the shadow res, the more pronounced. Can someone confirm whether this is a bug or intended behavior?
Thanks.
Bump because I’m also having this issue, would be nice to know if it’s intended or not
Weird, I think I saw the same thing today in 2022.3
The issue seems to happen at the edges of the lights’ cubemap, which thinking about it more, I suppose makes sense considering a nonzero radius causes shadows to sample from several points on the cubemap, and at the edges this would cause them to take samples from outside the bounds of each texture.
Honestly, I’m not sure there’s a fix for this, other than just not putting a radius on point lights. For it to work correctly, you’d need unity to take samples from several textures at once to blend them correctly, which I don’t think is possible at all.
Or maybe they could overlap the edges of the cubemap a bit, reducing the resolution of the shadow maps slightly, but it would eliminate the problem of sampling from outside the bounds of the textures.
The only way to handle this is to keep the radius to 0 or very close to it, the only issue, I am having, is not only it is a bug, but depending on the shadow resolution, the artifact changes its manifestation. I am just wondering whether this is the intended behavior or something that went under the radar. Hope the devs get to take a look.
