Kleiner Test (Vray VS C4D Physical Render)

Hi there...

As Maxon ships the Release 13 of C4D with an great new physical renderengine I was curious to test the speed against one great and production proven renderer "Vray".

Attached are some rendered Pictures to compare the quality and speed of the engines.

I have an Intel i7 980X (6x 3.33 Ghz with HT) 12 GB RAM

For the rendering wish both renderengines I tried to introduce as less noise as possible without pushing the sample settings to high.

Also keep in Mind that this is just a test of mine and different scenes mey produce other results!

General:
The Area Light Type was Photometric with inverse square decay (Vray and C4D)


Conclusion:
When it comes to rendertime C4D has managed to get a big step further with it´s new physical renderengine.
So why do you need Vray in future projects you might ask. Well the general approach to the Vray material is much more physically based then the ones in C4D with much more possibilities to go advanced. Also the GI method in Vray seem to calculate a lot faster then the one in Phys C4D (Although it has become faster then in R12) and the Vray GI has an unlimited ray depth! Also Vray offers some really unique advanced material solution like fast sss-, double sided-, override- and a very good displacement- material that the C4D current material system can´t match.

Also Vray offeres a lot of fredom using different GI algorithms that you can tweak to macht your special needs.

The downside of this clearly is that you have to know how all this stuff works before you can use it in production. And that can be a little tricky when you have a lot of choices.

So in the end there are no real 1st and 2nd places here. Both renderengines produce excellent renders both in quality and speed. While C4D physical renderer is really easy to use and Maxon took a big step to close the gap to its competitors although it can´t quite match the speed of Vray. Vray offers you maximum flexibility and an excellent material system.

Note:
As the materials in the renderengines are really fifferent the material renders are a little different.

I´m by no means perfect and those tests are not representable as a overall conclusion. These are just a few tests I made to see how the both engines comare. If I made some Mistakes in the settings and one engine might be faster with better settings please correct me!

The test I made was done using the Vray Brutforce engine that Stefan told me is not the one I should have used and is not (as I thought) comparable with C4D´s Physical GI solution.
With the appropriate Brute Force - Light Cache method Vray was a lot faster and the Material scene could be rendered within 10 minutes.
