Thanks!


anyone looking to learn V-Ray should get V-Ray The Complete Guide:

http://www.francescolegrenzi.com/bl...=vray_guide_eng

It's for Max but almost everything is the same. Then search for "Nederhorst workflow" for newer workflows based on the DMC sampler and Brute Force/Light Cache.

Also, I made a script called V-Ray Tuner that many people find useful. It has too many features to list here, so check it out:

Check the videos in the feature history to get an idea of what it does.

To add a single voice of dissent, I'm not impressed by Vray and will be sticking to mental ray for my work and art. I don't see any real benefits to Vray; render speeds are roughly the same for the same quality, ease of use is better in Vray but you pay for it with less control/flexibility. So while both are viable, I have no reason to "switch" at this point.

Do what you like!

For those on V-Ray, after you get familiar with the controls and the concept of adaptive DMC, this is a bit more in depth but highly recommended reading.

Using these methods I could get better quality renders for 30%/40% faster than the Universal method.

Just curious, in what way?

MultiMatte really spoiled me though. I heard MR is going to implement it too. But since my studio still sticks to Maya 2011...

There are 2 things I wish Vray would take from MR - shadow map, and a way to easily separate front-back scatter the way MR SSS does.

Vray is so easy to use

With Python V-Ray Scene Access, you can do everything, you have access to all attributes off all VRay plugins with the Python API.... It is like Renderman RI Filter ( .rib).
So, can you give us any examples pleases ?

And you can ask to ChaosGroup to give you all sources of the translator between Maya and Vray.

Thanks.

he means that mental ray offers so much control because, by default, photon rays are completely unrelated to the light rays. AMAZING!!!

he's just trying to justify his being forced to use mental ray for work.

I got to say the same thing we used to use MR at work ... I got Vray on my hands because I was tired of all the BS that you gotta to do MR sometimes to get simple stuff .... I showed the guys how to use it and how easy was ... presented to my bosses and we switched our completely pipeline to Vray ... and not regrets .... when you understand how to use the adaptive DMC is a pleasure to use ....

I wasn't really trying to start an argument or Sally-War on the topic, just hadn't seen anyone post that they were using mental ray still. Mostly because the mental ray people don't care, I imagine. Most of us that know how to use it don't really need ease-of-use applications - not that Vray isn't a great one, and a worthy competitor.

CGBeige is of course correct again: my mommy makes me use mental ray, as punishment for a rather difficult labor back in Korea.

I did try out Vray and it works great, perhaps the limitations were simply my unfamiliarity with it. I've tried it for Rhino and Maya both. Quick, clean renderings, but I couldn't see any reason to switch over for the sake of work. It doesn't really render quicker than MR, but it does set up a lot easier in general. This would have saved me a lot of time many years ago when learning Maya, but now most of the learning curve is over for my work - not that I don't have a lot to learn still, but I just do pretty interiors, nothing fancy for rendering here. Perhaps some day I'll make the switch, too, if it's easier to use for artwork?

I imagine since Vray is quicker to set up, it might appeal to my "artistic side" a bit more? The same arguments could be said for most other applications though as well, such as Modo or C4D. Guess I'm just too used to my Portal Lights. :(

Vray has portal lights as well, except you just check a box for it instead

Granted, the mental ray integration in Maya is still a work in progress. Change can't happen all at once. But change is definitely taking place. And really positive changes at that. Things are moving in the right direction. I'm quite pleased with the UI changes that have already happened. They make things much more clear. Also, the upcoming mila shaders and their close development with what's happening with MDL are excellent. Legacy workflows are being left behind in favor of modern, stream-lined workflows. The future looks quite bright for mental ray and lots great work is being done that is a direct result of user feedback. Users voices are definitely being heard and change is happening as a result. That could not be said a few years ago. I understand the frustration, though. Things in the past have been less than ideal. But again, all that is changing. I look forward to seeing how mental ray, and it's integration in maya, will develop in the near future.
