SR works on Max 8

I downloaded the demo and tested it last night using Max 8 and VRAY 1.5 RC2. It worked perfectly.
My render times appear to have been reduced substantially.

i downloaded the demo too. installation is running well, but when I open the solid rocks menu, I can't change anything in common setup, prepare scene, and render quality. and when I try to render nothing happened. can you help me to solve this?

thx!

I'm using Max 8, with vray 1.50. when I click the solid rock icon, the menu pops up, and a max script windows appear with a message that vray is not my current renderer, and asking me to switch to vray engine, although I already change my assign renderer to vray before. when I tried to change the vray global quality, an error messages pops up, MAXScript Rollout Handler Exception, --unknown property:\"gi_on\" in undefined.
is it compatible with my max and vray version?
thx!
