Vray_PPT / Maxwell

[jonnybefree]

hi to all,
i did a small test to compare Maxwell and VRay PPT.

this is the maxwell image:

Rendertime 90h. has reached sampling level 19.

and the Vray image:

Rendertime 2h for LC_PPT with sample size 0.003 / QMC 1.40h Subdiv.30
Total: 3h40.

Best greetings

nice!

as usual Maxwells rendertimes are a bit insane... But I have to say that all the materials look way better in the maxwell version than the vray version.

you could surely make the same materials (or even better im sure) in Vray, but then you would probably get higher rendertimes too...

just dont think its a very fair test from Maxwells point of view....

Not bad,
though You didn't match the light (Dark Values mainly)....

yes you're right, its just the rendering without post,

the materials looks a way better and light goes deeper in.
but its the first experience with PPT and i love it.

and its true, maxwell rendertime = VRay fine tuning, but i think for (fast) productions its a nice way.

...the materials looks a way better and light goes deeper in.

as you can see below, with a little gamma adjustment, the look and feel of maxwell, which I have seen does gamma correction of 2.2 by default, can be matched pretty closely. I even think that I prefer the adjusted Vray version, especially the sofas. In order to match even more closely, you should adjust your workflow of course with gamma correction in mind

your vray image adjusted with curves correction:

Good attemp Gijs,

The only problem is the Glass Bowl ... but it is due to the material I suppose.

yes you're right gijs,
i've renderd the maxwell-one with gamma 1.8.

its a way better with level correction.
thanks a lot

but with the glass-lamp, i dont know,
i've put the max-depth to 26 but there's still a black margin.

can you show us your settings on the glass? it does look rather glossy when it shouldnt be

nice comparison, as for me that's looks so really similar.

how about render usually method instead of use ppt to reduce noisy?

it would be better nice if there aren't noise.

Interensting comparison, well done

Concerning the glass... i get "similar" result in all my interiors, i can't never get bright and real looking glass as MW can do, even with caustics on

[Da_elf]

why are you using glossies on the light? if its a comparison between vray and maxwel then keep i to the same as maxwel which has smooth glass. the other thing with your glass is you dont have affect shadows turned on. that might make a difference. maybe your seeing dark because the glass is self shadowing itself more than it should since you need to turn on the option. you also would need higher settings on the glossies. but like i said it should be done without glossies.

@ipraiseg if your asking why doesnt he use a usual method like LC and IM or QMC rather than PPT its because its a comparison. it wouldnt be much of a comparison if yor using different render techniques.

I have to say that maxwell's image is more color correct, then vray's. This is not the first time I see this. By default, for some reason vray cannot emulate the colors transfer as correctly as one would expect. Im currently doing tests to see if I can narrow the issues.

[jonnybefree]

yes its right, its too glossy, but the maxwell-lamp is even a little bit glossy.
i've tried it with the maxwell material converter, but from maxwell - vray it doesnt work. so i made it all by hand.
i'll give a try to the affect shadow option. thanks a lot.

and its right its still less saturation in there, and near the window its too overburn i think.

I have to say that maxwell's image is more color correct, then vray's.

How do you know that it is not the other way round In this particular scene, the materials in the two scenes seem somewhat different in their settings.
