Thsi is a ring I made in Blender and rendered in Indigo. It only rendered for half an hour so I have provided a render with just a monkey that rendered for 11 hours too.
Pretty nice. Have you tried LuxRender for these? I believe LuxRender has a plug-in for Blender. It has one for Daz Studio, too.
stick the ring in the fire and see if the runes appear :) :D
just dont read the runes aloud.
the ring render looks nice, a bit grainy though.
Agree with Calico, give lux a shot. I think you'll be happy with the results and it integrates with Blender better than any other renderer.
