tahbnks in advance

Nope, Mental Ray v3.0 has no sub-surface scattering. However, Mental Ray v3.1 (which is in Beta at present) does have it.

I may have read that on the XSI Digest or on here, I can't remember.

I'm sure Softimage will take advantage of any new features Mental Ray v3.1 has in a point increment version of XSI v2.

mental ray 3.0 does have SSS but I'm told that it's slow. Also, I don't know how to access it. mental ray 3.1 is supposed to really speed this process up a lot. There are some really nice XSI 2.0 SSS pics on the Japanese Softimage site. Take a look at the very bottom of this page: http://www.softimage.gr.jp/xsi_img_glry.htmhttp://www.softimage.gr.jp/xsi\_img\_glry.htm

If anyone has any idea how to generate real SSS images in 2.0 (no matter how slow it might be) please let me know. I'd be very interested in playing around with it.

I'm not sure if this is something for you, but recently I played around a little bit with the volume effects shader. Maybe it's, what are you looking for.

Mental Ray CAN do SubSurface Scattering, because it's based on real physic simulation.

You only have to write the shader for this

So it's not a Mental Ray problem in itself, but question of writing a shader to do SSS.
