Using the same model from my previous V-Ray render of “The White Room,” …no problem at all when converting the materials to YafaRay–just some minor tweaks. What I like in YafaRay renderer are the soft shadows it produce from photon mapping. YafaRay’s strength lies on the right settings, and can produce great results like V-Ray.

The odd thing is if I change the glossy to a not-so-glossy in the material setting, it produces a black dot[s] like this sample:

Error with the material when anisotropic is enabled

Here’s the test render:

Black dots can be seen on the table

Hmmmm..it’s a bug. Checking the ‘Use photon map’ on the material’s setting, disabled the black dots I’m seeing.

See the test render:

========================================

The black dots are gone. I rendered the scene in maximum resolution (1920 x 1280 pixels) with 5000000 diffuse photons, final gather at 16 samples, etc.., and the time it rendered–7hours+.
