Vray, a biased rendering engine???
-
Hi Guys,
I was playing around lately with other rendering engine as my alternate for my Vray render capacity, and I came up to a rendering software showcasing their biggest advantage among other traditional rendering software, the unbiased rendering system. Some said Vray is manipulative and not create a real world light behavior similar to other traditional rendering engine such as mantal ray. but some said I have to activate something in Vray UI to mock a real world lights. What should I do to make a Vray result look realistic and unbiased??

The vray render engine is Biased, because it uses specific algorithms to simulate lighting in the scene. Unbiased renderers (like Maxwell) shoot a continuous stream of light which in time lights up all of the scene and gives you the final image after a lot of calculation (and time).
If you want to try this approach, you have to use light cache for both the primary and the secondary engine, setting one to medium settings and the other one to high.
With this approach, however, you lose the main advantage of Vray, which is quicker calculation using the combination irradiance map for primary/light cache for secondary engine.

I have to say that I have tried many render engines both biased and unbiased and I keep coming back to V-Ray every time. It will produce the highest quality renders in the fastest time (depending on your settings). With that said, I should also say that I have made a great amount of time investment in learning V-Ray and have years more understanding that the other engines. Use the engine that you feel comfortable with. I have seen amazing things come out of V-Ray that look just as realistic as anything that has come out of the unbiased engines.
What is 'realistic'? Doesn't a photographer setup custom lighting rigs and bring their RAW images into Lightroom or Photoshop and manipulate them to get what they want?

Presentation material is rarely "realistic" - they are always enhanced. The only thing that matters is that it looks good.

I agree with you guys, even though i tried some other rendering engine, either biased or unbiased I always coming back with Vray result and speed, but still i just want to continue exploring unbiased rendering software because of its future potential. I have read before that Vray is the present and (Maxwell) is the future of rendering, but the slow of the image production is bothering me to use it since it takes too long for it to finish a one scene.

That's exactly my experience as well.
