Physics rig does not take collisions


I must be missing something but I just don’t know what.
I have made a simple test rig to set up collision and physics with, using the Phat window having looked through the tutorial.
It seems to move ok in that window.

But when I try to use my characters sphere colliders to collide with the new rigs’ physics shapes I get nothing. The just go straight through.
The sphere colliders bump other objects in the scene fine. Their collision preset is for now set to ‘Block All’.
I have tried adding a physics material and tick generate hit events.

What could I be missing that stops me getting the interaction?

EDIT: Found it! Had just missed that the collision was turned off on my skeleton mesh. I suppose I thought it was a separate thing from the physics rig.
