Yes,

With the current .85 dev the shadows don't work properly or don't work at all.
I've tested a bunch of samples.
I don't get any console error message, so it's not easy to trace the bug.

i think is in shader
maybe hat object is understand like a skinned object
so position is tranform

It seems that the root issue is the same as #10754,
material can't be shared between normal Mesh and SkinnedMesh.

So separating depth/distance material for non-skinning from the one for skinning
may be the easiest way to fix so far.

The shadow problem on the example @lo-th posted was solved by
reverting c326466 except for Line76, and Line88.

Would you guys check if all the problems you ran into are solved with this change?
To @mrdoob and @takahirox

With the current build the shadows remain messed up for both static and skinned meshes.
Just test by yourself with a single model if

		model.castShadow = true;
		model.receiveShadow = true; 

It worked just fine before.

[mrdoob]

I'm aware of this issue. Planning on taking a proper look tomorrow.

I've tested both static and skinned meshes in all the castShadow / receiveShadow combinations.
I didn't notice any issue.
Well done!

[takahirox]

Thanks for confirming!

[mrdoob]

Ok, I think this should be now fixed. Sorry about that!
