Render Test: Mental Ray VS Cycles VS Luxrender by BrentOGara Render Test: Mental Ray VS Cycles VS Luxrender by BrentOGara
Edit 1/9/13 - Added Luxrender test of the same scene.

Just a test see how well Blender's (in-progress) Cycles render engine stacks up against the (somewhat more expensive) Mental Ray... and how Luxrender beats them both.

MR is standard in Softimage, and a very popular renderer for Max and Maya as well... since Autodesk owns them all, and MR works very well, it's probably one of the most used render engines out there.

Then there's Blender Cycles... still in progress, a GPU accelerated unbiased physically accurate render engine... and it looks just as good.

As an added bonus Blender is free, where the programs that MR comes with cost thousands... and yet, they all do the same things, in much the same way, in the same amount of time.

Luxrender uses some very nicely optimized bi-directional path tracing algorithms with full-spectrum lights (allowing for real dispersion and prismatic effects) to quickly render true-to-life images. You can even choose real world film stock and actual real world lights inside the render engine to exactly match the real world conditions (and that's a lot of real!).

For any 3D work dependent on realism (as so many of them are), having an accurate model of how light actually works is pretty important, and the subtleties of reflected and refracted light is often critical to making a group of digital objects feel like they are real, solid, and sharing the same space.

Here's hoping all of these renders have fooled you into thinking these are all real objects in a real box with a real light on top... and just take a moment to realize one of these renders "cost" thousands of dollars... and the other two were "free".

Problem with this test is there are no screenshots of the settings for each renderer.  So we don't know how many samples and proof of the samples used. So you can lower the sample rate on Mental ray to improve your claim.   You state 1024 @ 32 but we don't see proof of it.  I'm sorry Maybe i should get all 3 and fake a test just as you guys =3

Problem with this comment is there are no screenshots of the poster actually typing it. So we don't know if it's a sentient life form or a spam bot. So if, for some reason, some idiot did post a false comparison image, what would stop anyone else from repeating the experiment and discovering the truth?

Nothing. Nothing is stopping anyone with a decent computer and internet access from doing this same test themselves. That's how science works. You see an interesting result, and you try it yourself to see if it's repeatable.

You could, in fact, get all 3 and fake a test... but what would you gain from that? What would it profit you? What would you have learned? What good would that bring into the world? How would that help anyone?

It wouldn't even help the program you were lying in favor of, because anyone testing it would quickly discover the lie by direct, personal experience.

You'd have to be an imbecile to try and fake something like this.

You'd have to be lacking in critical-thinking ability to even believe such a transparent deception might work, or be a viable means of changing minds in the real world.

Don't be an imbicile, do a little thinking, try it for yourself. All you have to lose is your ignorance.

cycles is using osl by sony

Thanks for the info! :D I used the default SVM system for this render, but OSL looks cool, I'll have to check it out. Sharing materials between any OSL compatible render system is a great idea.

:D True, if you're talking about low cost, innovation, responsiveness toward users, sense of community, frequency of updates, or number and variety of add-ons and extensions.

Sadly, not true if you're talking about actual usage in the TV/Movie/Games industry. :(

my head hurts

Which part hurt your head? I certainly don't want my deviations to cause pain... well, not this deviation, anyway.
