Thanks Creck
Hopefully when David updates the site there might be a new forum for V-Ray, Renderman and such, Im not going to jump on the bandwagon yet as I still have a number of thing to finish but will be looking at these threads with great interest.............dave

Really looking forward to those sections, as I'm pretty interested in Vray ...

May the good times and treasures of the present become the golden memories of tomorrow.

Well guys, as there is already a thread about Vray, I would like to share with you the articles,which I found very useful to understand individual function of this engine, maybe you have already found and read it, but there they are:

Antialiasing and Color mapping
Indirect illumination
Irradiance Map
Light Cache
GI Engines Choice
DMC Sampler
Raycasting

After searching the web, asking questions around, watching videos, this thread and others references, that's it, I just couldn't resist the temptation. Just bought V-Ray version 2.30.01, waiting quietly for my dongle to arrive.

They don't have the demo version available yet for Maya 2013.

Glad to be back after a month. Had to step out to sort out some issues.
I installed V-ray and went through some video tutorials. Amazing and blazing fast indeed.
But don't ask me much, as I'm still learning it.

Decided to make a quick video showing a sphere only to gives an idea.

My Specs:
i7 - 2.8 ghz
16 gb rams
gtx 560 Ti

The reason people use Mental ray is because it's free ( just my opinion), development is poor to say the least.
I also understand that for larger studio's it's more economical to hire a renderwrangler to patch it up so the renders get done, but when you are a freelancer or a small studio I would definitely advise using a solution like Vray or Renderman...these are better renderengines because these developers focus on its development ( the same reason Zbrush is better then the artisan brush in Maya)

umm, that video kinda showed nothing really, rendering a sphere isn't such a good test. user added image

...maybe if the sphere had DOF, motion blur and a glossy material and maybe a few dozen more friends and soft shadows casting on something.

Yes the scene is simply but it clearly shows the responsiveness of v-ray RT (real time) vs MR IPR. For more complex scenes the difference only becomes greater as v-ay is far more efficient with memory then MR + IPR.

I think there were some very good examples of the RT render performance in the original demo video.

I just wish the full blown v-ray was bundled into maya as I really dislike mental ray.

yeah, its shows the difference between real time rendering and IPR which isn't really fair.
show the difference between vRay and progressive rendering in mental ray.

Unfortunately they have not integrated the progressive rendering into the maya gui yet and the only scripts I have found on creative crash either only work with maya 2010 or conflict with iray forcing you to constantly remove all the scripts from your scripts folder.

Trying to use the command line progressive rendering commands are once again like everything in mental convoluted and overly complicated.

However, I did give it a look and honestly v-ray is still hands down faster, makes better use of memory which is a big deal as it means you can render much larger scenes then you can using MR, and most importantly is still far more intuitive and easier to use, which all translates into much less wasted time fiddling with MR's poorly documented dials and knobs and switches and more time getting work done.

Most people do not even know progressive rendering in MR exists. I played with it way back in maya 2010 when it was implemented and found trying to use the command line options to be a real pain in the ass and literally defeated any time savings gained by using it so I decided to wait for it to be integrated into the gui and here we are three versions in and still no native gui support.

Thanks dom.

I am still a bit hazy on MR progressive (CPU based) vs iray (GPU based) render engines. I think progressive was introduced in the MR render engine included in maya 2010 and both progressive and iray are available in the MR version included with maya 2011.

Perhaps the delay in adding a native gui is because they want to integrate the two so you have a single engine with a choice between CPU and GPU rending.

V-ray RT already has a simple switch to chose between CPU and GPU rendering.

Its all Chinese to me LOL...I know one thing...even on my new tower...MR shits itself constantly.

Spec
i7 quad @ +3 ghz (cant remember)
16G Ram
gtx 670

and it still crashed LOL. I will say that trying a simple displacement I cranked the terrain plane up to 300 divisions, did it fairly quickly but died at 500. I did a really good random terrain in 6 mins...3 with cloud difference in PS the 3 mins in Maya. No sculpting LOL IM lazy...PS to Maya is so easy.

that's quite the machine you've got there mate, is it a quad or a dual quad processor, since if it's only a quad one, I think that that can be a bottle neck or at the very least your 16 GB ram will not be fully utilized...what kind of disc(s) do you have ( SSD, SATA/SAS,SATA/SAS in a raid config)

If it's a big scene you have to alter your BSP setting in the renderglobals, nowadays it's standard on BSP2, then you have regular BSP (where I normally set it initially)and large BSP, if your scene keeps crashing on memory stuff each time you might wanna try large BSP
