3DWorld review: VRay 1.5 vs Brazil V2 -> VRay SLOW!

[cecofuli]

Hi guy,

what do you think about this comparison between Brazil 2.0 and V-Ray 1.5?

Brazil 2.0 is so fast than VRay 1.5, or what?

Well, its an amateur comparison...
Terrible secene to do the testing on. And so none of those results can be conclusive.
Im sure that brazil 2 is fast.
Really tired of the which is faster comparisons nowadays.

opss...sorry . Anyway, i quote Morbid Angel: very stupid and inconclusive "pseudo-review"....

[trick]

Well, its an amateur comparison...

Wasn't this comparison done by the guys from Uniform ?

[Neilg]

They cant have spent much time on it if so.

I dont really care who did the comparison.
When you compare renders there are certain things you must look to, in order to get correct speed/visual result.
In most cases if the comparison is correct, visual result should match quite closly.
In this result visual difference is significant. So is the render time. Due to the points outlined in the link, there are some major errors done in the comparison.
Secondly the scene in question is a bad choice; bad lighting, bad texturing.
What you must do to compare renders is render separate components one by one, i.e. reflections, shadows, gi, refraction, displacement.
Evaluate each one on its own. Then combine each ofthe results to total, and this will be your correct result.
If for example you place a sphere on a plane and shine an area light at it, and compare pure glossy reflections from direct and indirect then you can correctly judge render time differences.
You must also account for things like sampling algorythms, filtering alrogrythms and so on.
If you compare a vray render that uses 1/24 samples of adaptive dmc vs mental ray 1/3 adaptive subdivision then the actual number of samples taken will be significantly different. That alone will alter the render quality and also time required.
The list may go on....

haha...basically what I said. But in a brief defenition

Vray v's brazil its a no contest for me so I'm not going to waste time on that, however uninformed articles like such only reiterate what I have thought for the past few years i.e. 3D World is nothing more than a rag, I see better tuts, product reviews, industry news floating around on the web (all for free). I recall posting a question on their forum about how they can actually charge people €10 approx for such low quality material, do we really need a another f&%^&ing tutorial on how to model a hand???

[^Lele^]

I hope I'll be able to finish tweaking the scene for QUALITY, as I honestly can't be bothered to get into the "mine is bigger than yours" debate.
Just so I can show VRay doesn't "cheat" normals, or reflections, or GI, as stated somewhere else.

I was under the impression that the author of the blog works for Brazil...

[stilgarna]

As always... Mine is bigger than yours

It's very hard to compare 2 renderers...
You can compare feature by feature, not an entiere project... too hard...


Best regards.

sheesh. not sure what the point is comparing things.

guess its the oldest one in the book (just don't mention the war, must be the other one)

I love vray, and now i too have sinned. Moving some types of projects over the renderer called Brazil, and Im happy to use both. Right tools for the job.

back on track. 3dworld mag has been good over the years, but the need to include everyone has meant its a bit short on quality stuff, very short. CGI magazine, god rest its soul, was much better. a pro mag would go down well, but like mentioned most good stuff can be found on the net.

cgtalk has gone the same way. loads of poser people, loads of cracked software people, and loads of noobs asking, how do you do water, how do you extrude a poly, how do i make my render look like ILM's etc etc.

[stilgarna]

It could be interresting to test all renderers feature by feature :

Only the mtion blur, only the displacement, only heavy geometry, only heavy geometry instances...

Best regards.
