A little V-Ray fun with the Caligari Radiosity Room. :)
About the scene: One spotlight, rendered in V-Ray with global illumination and caustics. |

Pretty good! How long did it take you to create this experiment?
And one question......How did guys create Vray similair results in TS6.6 before TS7 came through? |

Thanks guys.
Birdnest, How long this took: (approximately)
Scene: about 10 minutes to model the mirror ball, about 10 seconds to load the Caligari Radiosity Room scene and swap the cube out for the mirror ball. :)
I then spent about an hour doing test renders to decide on the V-Ray settings. Each frame took about 30-40 seconds to render (love this Athlon dual core! :) Total time to render 120 frames to *.tga about an hour and 45 minutes.
I had tried to do something like this back in tS 5, of course I had to fake the caustics. The best results came from using a really bright shadowcasting light which I shone through a rotating shelled ( hollowed out) sphere that had lots of holes booleaned out of it. It didn't look too bad, but I like this a lot better. :) |

A cool variation on the traditional 'shiny sphere' picture! Wouldn't it look great with some volumetrics applied too! Of course your render times would increase accordingly!! |

mmmm....volumetrics..... y'know, I just might have to do that :)
Very tempting! Of course this raises a question...do we even have volumetrics in V-Ray?? I must look into this. |

Pretty cool, b_scotty! :)
I would like to see how caustics w/ volumetrics turns out if you do it! |

I dunno if there are volumetrics in Vray or not - I don't have V-ray. You could fake the volumetrics the old fashioned way, with mostly transparent glowing cones. V-ray certainly does transparencies!! Just a thought.
Let us know how you do with it. |

I don't believe there are volumetrics in Vray-nor fog and DOF...however, give me a minute and I will try. Pretty sure these are LightWorks things though...:o |

I'm afraid Splinters is right, volumetrics are not currently in V-Ray.
However, I have a few ideas to try faking it. :) I'll post any results when/if I get them :P |

Yeah, sorry about that...my minute was snatched away from me by an over-enthusiastic student. However, it does not work as scotty said...:o |
