Renderer differences?
I was wondering what differences there are between the non-pro and pro renderers.
Like YafRay and Blender and PovRay and such, to VRay and mentalray.
How are they better? Are they faster on average? What stuff do the pro ones have that the free ones don’t?
I think you’ll find this really interesting.
Yes, it is very interesting. Thank you!
It was interesting? really?
I came away from that page knowing nothing more than when I went there…oh…apart from the fact that every renderer under the sun is faster than winosi 
Worst comparison ever!
Hey, I was beening polite! And besides, I have more renderers to look up now.
My thoughts exactly. 40 hours for something you can render in 20 minutes with other renderers?! Sheesh! Although, it seems WinOSI is not meant to be used for 3D artwork rendering, but more for rendering very photorealistic scenes…but still very slow.
That link was shown to give an idea of renderer’s ability.
WinOSI is ment as a test of a new ideaology of rendering lightwaves. Very slow, yes but give it 5 days to render it its looks damn good and real. Its not meant for production, just a test of algorithm.
Your questions are sooo open that it will take many lines to answer. Obivously Pro Renders Have support and intergration into major 3D applications. While free ones are “take with what you have and work with it”
I cant tell you which one is better, its all about what you want down and how long your willing to wait.
WinOSI is meant to be extremely realistic and physically accurate, but at the expense of speed. Personally, I think that page is a perfect example of what it’s really good for: generating reference images.
