With:
V-ray RT that uses the GPU
V-ray Wrapper materials
V-ray Express
And HDRI Light Studio support
Wow! Looks great! V-ray Express would save many non-render geeks much time in set up.
Vray RT (CPU or GPU) and HDR light studio with the light paint feature helped me a lot for jewelry/watch rendering. Simple click on the model at the Rhino viewport and the light is placed. Also there are dozen of little additions that help for my daily usage.

I really liked that in the video…where one just clicks on a part of a model and the light is automatically positioned.
How stable is Vray RT in Rhino? Have you tried any other GPU renders in Rhino and if so, how does it compare?
Thanks.
Vray RT is stable, but I used the CPU engine only, because my GTX285 isn’t supported (I stick at this card because the Rhino display pipline 
).
Since I use a 32 core machine here I don’t expect to much speed gain from a graphic card. Also it looks like a well adjusted biased rendering is faster than the GPU brute force engines. So far my impression.
Any advantages over Flamingo nXt?
How I imagine rendering: Assign colors, tweak materials, select some kind of HDR lighting, and that’s it. Normally, I don’t want to set up lights, do post processing, etc. It’s just for previews. The more photo realistic it looks, the better. That being said, of course, I want to have the option to go beyond a basic setup, for special purposes once in a while.
I downloaded the demo and was anticipating a little more speed than was there with the RT. Just even some simple geometric shapes were somewhat sluggish.
I’m certainly no expert with Vray and the machine I have isn’t cutting edge, by any means, but find Neon, Arion and Octane to be much snappier in screen updates. I haven’t given up on Vray RT but am a little underwhelmed for first impressions.
Yes, the display could be faster be updated. For me the combination of RT and the full HDRLS integration is the great deal.
Yes, I can see where HDRLS integration would be very useful. I like the fact they have come down in price and up in features, making the app very attractive.
I downloaded the demos for each of Vray and HDRLS…quite a nice combo. One of the issues I had with Vray before (and maybe it was possible to do) was the lack of control to rotate or move an environment HDRI around with any sort of immediate feedback. This combo really opens that up.
So much good software available for Xmas time!
I hope Rhino will get a RT display mode where the HDRI is direct shown in RT. I didn’t test it, maybe Rhino updates the background.
Sidenote: I have set the WINDOWS temp dir to a RAM drive, so I get a write rate of few thousands MB per second. (QSoft RAM disk)
I’m not able to get RT mode to work. any tips?
If you run it- it will fall back to RT cpu render if no cuda card is found.
Opencl RT has to compile first. this can take a while…on a q6600 a long time…really long time.-hours.
Do you have a card capable of Cuda 2.0?
Yes - I have a Quadro 4000 using the most recent performance drivers.
all proper vray services running.? -and let through proper firewall permissions.?
-clean out old vray installs.-do this.
@CPearase - Ok. I can clean out old installs. What services should I look for? (V-Ray 2.0 renders fine)
I could be wrong here but it looks like vray looks at a cuda card as sort of a distributed render device?. anyway you need
the spawner running.-XMLDRSpawner.exe
-you can always fall back a couple of version numbers on your video driver.
-never had a quadro-those different certified/partner drivers etc not sure how that works.?
your hunch was right! I had not installed the distributed render service - a re-install fixed the problem. Thanks so much.
no problem.
-you owe me a cookie.
