I discovered that two of the Ambient Light > Backgrounds (Constant and Gradient) did not produce light when UseBkgnd was enabled under YafaRay Render Options. I found out that there was a change that went into effect with YafaRay 0.1.2 that moved this setting to the Background settings for Constant and Gradient. They now work the same as Image and HDRI Backgrounds. YafaRay 0.1.2 Notes. Note that this now works for Direct Light, Photon Mapping, and Pathtracing.
I have updated the Wings3D Yafaray plug-in to reflect that change. I also did some edits in the help info under Edit > Plugin Preferences > YafaRay.
I changed the default setting for Gamma under YafaRay Render Options from 1.0 to 2.2 based on what I have read in the YafaRay forum. YafaRay Gamma. The info is a bit confusing since it applies to Blender but in tests I found that Gamma at 2.2 seems to give better results. I may be wrong and can change the default back to 1.0 easily.
The updated version is on my Wings3D page. I have tested it on Wings3D 1.5.3 and everything seems to work.
You will also want to get the YafaRay 0.1.5 SSS build by Povmaniac that is on my website. Using the official version of YafaRay will not give you access to Subsurface Scattering.
