Rigged object suddenly not rendering I've been working on this model for days, finally got the texture right and the rigging right (ish).  Until I started posing the rig, everything rendered beautifully.
Then I had a boatload of trouble with the rig caused by a very large cat, and I ended up having to unparent the mesh from the rig and re-parent it.  Ever since then, I have not been able to get the mesh to render.  Spent hours searching the internet looking for a solution but so far no suggestions have worked.  I'm using Blender 2.78 on a Macbook Pro.
Okay, found the problem; somehow, under Duplication, I had Group chosen instead of None.

I blame the cat.
