Vray?

32 posts in this topic

im thinking of upgrading to a decent 3d rendering system.

i use GI and AO otgether more recent and having to wait 2-3 minutes per frame

(when you have a 30 second sequence) is not too handy with deadlines and use

of time.

is vray any good?

i have a friend who uses finalrender on the pc, i want to buy this for mac but they are taking sooooooooooooooooo long

about finalising / releasing it. can anyone shed any light on the matter (pun not intended)

is vray the way forward at the moment or is there any other software that will drop my high end renders down a peg or two?

does anyone know how much more performance vray has rendering GI and AO over the standard c4d renders?

look forward to hearing about this.

Vray is good for some things. I havent found it to be very fast. You can try a trial for free. I dont think it plays well in animation, mostly for stills. It does an awesome job when you learn how it all works. There is a steep learning curve to get the most out Vray. You have to use Vray specfic materials or convert C4d materials to Vray (via a plugin) you must use a Vray camera and Vray lights, There is a lot to learn but does some awesome still images. There is a forum Vrayforc4d google it. It is expensive too. C4d r11 AR is awesome if you learn how to use it and set up lights and create materials, Hell it is awesome if you use auto lights, Very simple to learn also there is a tut flotaing in the members section to show you how to cut Gi rendering in 1/2 if you so choose to use it. Good Luck, Tom

Final render is very good and very unsupported at the moment,

FR uses natively c4d materials and has its own material xpresso editor which is easy enough to learn.

plus it has corner smoothing in its shaders, so no objects has sharp edges in your renders, no other render or shader has that.

learning curve is kinda low for FR

Vray is a better engine with exhaustingly high learning curve and waiting times for your renders.

If you go vray, you'll need a very fast computer with dual or better cpu. (most say its worth it)

If you go FR, single cpu with 2gig of ram is kosher enough. (no very much use by many)

I personally like either FR for its ease of use and uses cinema mats natively end get near perfect render, not sure on the animation though.

From what I've read and heard vray is better with animating

Or you can just use cinema's render engine, which is pretty good by itself.

I'm Working only with vray - great results - stills and animation. It takes time to learn all the little things inside, but you can achieve beatiful results. It's not cheap, but we are getting free updates until version 1.5 (which will be exactly like the max version-now we are at 1.1 and some things are missing)...

As said before, you can download a demo for free, and play with it a little....

This is the official forum: http://vrayforc4d.com/forum/index.php

This is official site: http://www.vrayforc4d.com/

And this is the manual: http://vrayforc4d.com/manual/

I think the biggest disadvantage of the current AR3 is the post effects. None work very well, and what's even worse, they cannot be combined (DoF, MB, Glow, etcetera). So I think this is one of the best reasons to switch to vray. GI and AO is great in Cinema, even in full animation (just don't use the full animation mode). I don't think you can get better rendertimes with vray in that area.

As usual when the subject of Vray comes up there's a lot of miss information doing the rounds.

First off, Vray produces spectacular animations. Have a look at this, 100% CGI done in Vray

http://swaystudioftp.com/Pontiac_Mine_PR.htm#

This is the Max version, but the render engine is identical, only the bit that joins the render engine to the host application differs. This would be possible in the C4d version (I just like this example!).

Second is the materials issue. This one is summed up by a comment someone made here some time ago which went: "Vray would be perfect if only it could use C4D native materials..." That kind of sentiment can only come from people who have never used Vray. Once you get over having to convert your legacy projects (which is not much of a pain in itself, and often you simply replace rather than convert), and spend a few weeks starting projects from fresh with Vray materials you'll never want to go back to native C4d materials. They seem incredibly crude once you've got used to Vray's.

Another one that often pops up is that Vray doesn't work with Body Paint ("... it's a deal breaker!"). I use it with Body Paint all the time, there's a simple work round.

And speed. Your render speed will always be dependent on what you're asking your render engine to do. You think 2-3 minutes is too long? The current job I'm working on is running between 40 minutes and 1 hour ten a frame for a one minute animation. That's why God gave us renderfarms. If 2-3 minutes is a stretch I'm wondering if the animations you're working on even need GI in the first place. I take it we're not talking about stuff like the car ad above. And if you really don't need GI then save yourself a lot of agro and avoid. In general I think Vray is a little slower than FR (but produces much nicer images) and is much faster than AR. It produces nicer images than AR, although the gap has narrowed somewhat since the introduction of AR3. Also AR3's non GI renders are pretty fast and when you factor in how much cheaper AR is than Vray you have to take a minute and ask yourself if you really need whatever extra Vray brings to the table.

Vray isn't perfect, but none of them are. And this is another thing that happens in these threads. For some reason Vray's failings are cited as deal breakers for a lot of people, yet AR's failings seem to get a free pass. In one sense, as AR is made by MAXON itself, AR's failings are less acceptable. And as for the learning curve, most people's troubles come from the fact that it works in a different way to AR so you're essentially an old dog trying to learn new tricks.

I love Vray and use it all the time. Nevertheless, I'd still advise people to think long and hard before shelling out. Do you really need whatever it can do above and beyond AR (what else could you do with all that money?)? Do you even need GI in your animations? And don't forget to ask ourself if you even need AR - C4D turns out fine renders straight out of the box without even resorting to AR...

a still attached showing my result with AR and AO and one without.

if anyone knows how i can achieve this look and not use GI and AO then i would love to know. its the little thigns like the GI reflection

in the ground and the solid crisp (bright colour) that i have not achieved with basic AR. if i get AR3 willi see any improvemetn on 2-3

minutes with these settings (attached also).

BTW - the render is Best and Animation 1024_576

look forward to hearing if there if an alternative to GI and AO with this kind of look

Graham

BTW the pontiac work is beautiful and im def not working to that level but as the examples show (picture 26 being the none GI and AO)

its simple things that im not getting such as shadow under car and the nice white refelctions on the number to the rear

i think i need some help with the relighting to cut time. i have tried some AE grading / adjustments but its not looking as the desired frame

is looking

It's not your render engine or Gi that's the problem it's your basic lighting set up that's amiss. What you have in the first pic is easily achievable without even using AR. How are you lighting this?

You know.....if your just doing simple scenes that are not to complicated, you should just try omni light with shadows.

may a mixture of spot and omni light, just a couple though with soft shadows on.

I think your trying way to hard.

That's your problem. Here you go. No GI, AO or even AR. Just the most basic C4D render. With a sphere for reflections: 56 seconds. And you could get that down by dropping the resolution of the image used on the sphere. Also much of the time comes from having a blurry reflection on the floor. Without the reflective sphere: 5 seconds. It's not an exact recreation of yours, just a quickie to give you the idea.

Cheers

And here's the images...
