Vray for XSI beta

[smtezo]

I heard there is beta version of Vray for XSI out there, does anybody have any details?

[wurp]

yes, me and other people are already playing with it.

if you want to test it send an email to vray@chaosgroup.com and ask for it, you will need to sign some stuff but they are pretty quick to respond so it shouldn't take long

Great! I have already emailed them.

Thanks

I've never messed with vray, what are its advantages/disadvantages compared to mental ray?

[wurp]

this has been discussed to death, it's simply a different renderer (focusing on raytracing mostly like MR), it's being used a lot for architectural viz and has very good GI capabilities, I guess you'll have to try it out yourself to find if it can offer any advantages over MR depending on the kind of work you do.

It uses a different approach to GI (Irradiance Maps) which is a kind of a "cheat" but results in blistering performance. It almost has a "nice render button" approach to rendering, which can definitely save you when deadlines are looming. However in terms of power and customizebility I would rate mental ray way ahead, who knows maybe with nVidia now in the picture mental ray it will get the speed boost long overdue....my two cents

I held up my move from Max to XSI for over a year because of V-ray. I waited and waited, and then finally decided that mental ray couldn't be that bad. (Not to mention that Soft was about to jack up the price of Essentials by a grand.) Now, after spending lots of time with mental ray, and even taking a 3-day course offered by Mental Images, I continue to look forward to the arrival of V-ray, though not nearly as desperately as I once did.

Quality wise, both renderers produce nice results. In fact, I find the results I get to be quite similar in appearance. Speed wise, V-ray wins--there's no two ways about it. Call it a "cheat" on their part, or whatever--but when the focus is the quality of the output and not the route the numbers took through the streets of renderland along the way, the way in which V-ray does things just makes more sense.

That said, it's no rendering miracle. For example, just turn on motion blur for a single object in the scene and all your beloved speed takes a long holiday. So, you'll still resort to tricks and such once you get into serious productions with it. In addition, animation flickering can be an issue too, though I have to admit I've had a tougher time overcoming that in mental ray than I did in V-ray.

V-ray is great--no question. But it's not going to give you the motion blur or displacement "magic" of 3Delight while also doing the photo-accurate raytracing of mental ray. It suffers the same setbacks of raytracing that affect mental ray, but because of its irradiance map method of calculating the effects of Final Gather/GI, you start out with a huge speed boost, so you learn to love it before you start to hate it. With mental ray, you pretty much start out hating it and have to learn to love it.

hey guys with beta vray, can u post us some screencaptures, render tests or anything like that?
thank you

[wurp]

hmm, no, thats why we had to sign an NDA, so that details regarding the beta wont leak out :P

if you want to get on the betalist send an email to chaosgroup and you'll need to sign some stuff.

I'm using the The vray for Maya beta and have used the max version.

I would say that Vray is faster but much less tolorant of bad modeling than MR. But if I'm not mistaken the new Mental ray that will be in XSI 7 and is currently in Max 2009 has the irradience map approach in it as well. I could be mistaken as I have not been able to use either. and While Vray is definatly faster "at most but not all" I would not call it blistering by any means. I have found that for animation you have to jack the setting up so high that it is only marginaly faster if at all. At least that is my experience using Vray 1.5 under Max 9. As for maya it would say that it is pretty much the same. not all of the nodes are there becasue some are not needed do to maya already having something similar. but it's implementation is already lightyears better than mental rays.


But this is a softimage forum so i'll shut up.

The render I'm most looking forward to for XSI is going to be finalRender. It flicker free GI in animation is a dream come true. They are bringing it to XSI as we speak. this was a big deciding factor for us making the move to XSI from maya.

[giant551]

To be honest where Vray shines head and shoulders over MR is for interior arch viz. Ive been using the max version and the ease of setting up an interior GI scene very qiuck and easy for a very good quality result. I think if you have the knowledge and the time mental ray can match the quality of Vray but for ease of use Vray wins hands down, but lets face it, i should think so for the cost of it!

Ive signed up for the XSI vray beta so i am looking forward to seeing how it works within XSI. I

flicker free gi...its just german marketing

[thiago]

Actually they can get flicker free, but they get heavy as hell too.

[calmasacow]

Actually id does have very flicker free that is not all THAT heavy for what you are getting but it does tak a lot of precalculation.

and they have seperate alogorithms for the computation for camera only animation versus camera and/or object animation.

It is quite nice I have been able to do things that would have killed me in MR.

As for Vray It definatly works better for indoor stuff rather than outdoor. As for animation I think if they came up with an adaptive cache system such as Final Render it would prolly be the really work for animation. Right now if anything other than the camera moves forget it. Also a short comming I have noticed is the DOF and MotionBlur. These things are slow on just about all renderers but they are real slow on vray IMHO. This is an area that Fianl render is really good though in IMO. The hit for really drastic motion blur and DoF is not near as bad comparativly. Think that once FR Stage-2 R2 is released it will be a strong contender.

As anyone tried the new Fryrender with XSI yet? comments?

[giant551]

I have had ago with fryrender briefly and to be honest its only good for stills. You can get really good results if you have the time to wait for it to render, like Maxwell its just sooooo slooooow...

[ThE_JacO]

It's not slow actually, at least not in its domain.
If you talk about maxwell or fry you have to keep in mind they are unbiased renderers.
Saying they are slow if compared to something out their domain would be like saying that MRay is slow compared to OGL :)

[giant551]

yes it is slow actually. Unbiased renderers are slow only good for stills, i didn't compare it to any other renderers. Your just nitpicking:D

[calmasacow]

yeah just checked out the demo and crap man that is slow. seems to be just another maxwell

[ThE_JacO]

Of course it is, they are both unbiased rendering engines :)
They aren't supposed to go against PRMan, 3Delight or MRay, they are supposed to have a brute force approach to accurate realism.

If you're after an alternative to MRay or one of the RM engines you DO NOT look in the direction of Fry or Maxwell, as simple as that ;)
