Have you tried adjusting those meshes’ Distance Field Self Shadow Bias value? It looks like the ceiling mesh is quite thin so DFAO from those meshes is bleeding to the other side. You might want to increase Distance Field Resolution scale of those meshes as well.

Hi there,
I have the same issue.
Did you manage to figure out the problem?

Make sure walls are at least 10-15cm thick. Check the distancefield debug views. Make sure meshes like walls and ceilings are broken up and separate.

hi ZACD,

thank you for replying.
I am really struggling with this.

The ceiling is 50cm thick and is a separate object.
If I move the dogs up in z-direction the bleeding gets weaker.
it feels like as if a radius is determining how big the impact to other objects is
i have attached a jpg showing the issue.

Any further help is really appreciated!!!
