This fox 3D-model was made years ago, now I re-activated it to test a new renderer called Redshift (www.redshift3d.com). The image above was rendered with brute force global illumination using a HDRI within a few minutes. Rendering a setup like this in MentalRay would take hours, finally rendering furry characters is real fun :)
Done with the best 3D software on the planet - Softimage XSI.

Thank you :)

Great job!
I'm very curious about the technical side of that. What's the memory usage when rendering? Fur tends to be terrible with this (at least, realistically made in Blender, together with long hair, it can go past 4 GB).
What kind of GPU was used here? While I technically could use GPU for my projects, the RAM requirements make this non-practical. Unless I rob a bank or something. :/

Thank you!
Memory usage with 600k hairs is about 1,1 GB, the image was rendered on a GTX 670 with 4GB. Redshift is amazingly memory-effiicient.
I am currently learning Blender aswell, but don't have experience with fur so far, therefore I cannot give you any expert tips here.-
Well, I'm messing with fur in Blender since years, so I may have some tips actually, if you want to try that. :p
Cycles (Blender's path tracing engine) handles fur seamlessly, but the memory usage can go high, and there's hardly a way around it if we want realistic results. Biggest memory hogs are 1) hair curve subdivisions, 2) random roughness. Can't resign any of these for realistic effect.
The memory usage is my personal pet peeve, as is has prevented me from using newest versions of Blender for 1.5 year! The devs made a choice of increasing the hair rendering speed at the expense of RAM usage going almost twice. Guess that worked with human hair and simplified cartoony fur, but for my projects was a showstopper. Just building the data structure for rendering had great trouble. Had to stick with an old version of Blender where it worked good for me (and they come out really often, each with new goodies) until the situation got more manageable again.
To be on the safe side, with no worries about limitations, I'd need at least 6 GB GPU. That's not gonna happen very soon.

Thank you for your tips. Indeed, keeping hair subdivisions low is important, not only in Blender.
If you need a graphics card with 6GB, the best option would be a GTX 780 with 6GB, they are sometimes available at Ebay for around 300$. I have this card in my computer and I am very happy with it.
