Floating objects

[Fisher]

Hey what's up guys? I feel like I haven't posted anything in a long time. I guess I've been feeling uninspired or unmotivated... blah. I actually made this peice a couple days ago but can't for the life of me figure out why it's levitating. I know Jelmer says that a lot - sometimes things look like they're "floating". Is there a way to combat this? I thought it was lighting but I tried so many combinations and this looks the best but it still looks floating on the front edges (red lines). In the image theres a skylight and two MR Spots at angles to the camera.

I can assure you the "stone" is not above the ground plane. Does anyone know how to unfloat floating objects?

thats to do with the bleeding or global illumination, I have a similiar problem with the materials I ma using for my tyres for my batmobile, even though I sink the wheels below ground, the tyres look as if they're floating.

At a gues, change gi, or materials, let me know how you get on?

hmm yeah there aren't enough dark shadows around the base of the stone, so increasing the quality of your lighting (for instance, if you use mental ray, increase the final gather preset to medium or high) should help a bit at least.

If nothing works, just render your image, go into photoshop, and 'burn' some of the edges near the stone.
