I have used viz and am fairly familiar with radiosity but i want to move into the mental ray engine. I have done the tutorial in the help but found that it doesn't really help me out with exterior renderings. Is there any one out there with a good exterior tutorial? Is there any settings that need to be changed in viz that i might not be doing to go from scanline to mental ray? I seems that my rendering are always missing light (large black spots, or no light at all).
I have seen some great stuff from mental ray, and want to do the same.
any help appreciated.
Thanks
Justin
