r72: receiveShadow some way to improve?

[Freeman555]

hey guys,

There is some way to improve "receiveShadow"? Self shadow has some strange disorder (looks like a black waves), pls take a look:

I thought shadowBias or something like that would do it but maybe it's more the shadow map size after fiddling.

This is bizzare...

Seriously though with the Physically Based value -0.0002? aka zero

Line 88 in 17df4c4

shadowBias: -0.0002,

Notice the difference in the shadow penumbra with the shadow map at 4k

this camera perspective reveals an obvious bug with the spectacular too right?
Was the aliasing at the edge of the shadow your issue?

Yeap, it's a bug with light on shadow.

BTW Your solution fits me, thanks.

Not really... You can "fix" it by doing spotLight.shadowDarkness = 1. But yes, I would argue we should probably remove shadowDarkness altogether.
