I don’t really understand why the shadow computation behaves like it does. I’ve created a PG to show the problem: https://playground.babylonjs.com/#B48X7G#48
I’m using the PCSS shadow which works fine if I use a spotlight but the soft shadow gets basically completely hard if I use a directional light. Simply comment in/out the SpotLight/DirectionalLight in the PG to see what I mean.
Hope someone can explain to me what’s going on there.
