Spine Shader Receiving Projector

gycot

I added a drop shadow to all my spine skeletons using a Unity Projector. In the SkeletonLit shader, I see "IgnoreProjector"="True"
But I still see the projector drawing over my spine animation (the shadow is on the ground, and you can see it drawing over the feet)

I tried setting "Ignored Layers" on the project to include the Skeleton Animation object, but it still drew over it.

I tried changing my Projector shader queue
"Queue"="Transparent"
"Queue"="Transparent+10"
"Queue"="Transparent-10"
But the projector still drew over the Skeleton Animation.

The only way I could get it to work successfully is to turn on the Spine Shader's ZWrite (which results in no shadow overdraw, but as expected stops drawing the spine animation correctly)

Is there any way to get a Unity Project to not draw over a Spine asset?

I have to admit, I'm not familiar with the situation.
But as you've noted, the code does explicitly tell it to be ignored. So that's weird on Unity's end. You can also see that apart from the shadow pass, which you can remove if you don't use it, Spine's bundled shaders are really vanilla shaders.
From what I've little I've found though, it has as much to do with the projector's shader as it does the materials receiving it.

Fixing it by having Z-write OFF makes no sense to me.
