How to : luminescent stone (Alabaster)

[fraggle]

Hello,
I'm tryiong to find out how to make a luminescent stone material like Alabaster. I've tried the following :
1- with a vray light plane on the back of a semi transparent material apply to the mesh
2- applying a vray light material within a stone map

None of it gave a good result. The solution 2 even create a lot of blow/spot during render in some other part of the render.

Any other idea?

You probably want to look at the sub-surface scattering material. http://www.spot3d.com/vray/help/150S...ss2_params.htm
