Yafaray Render not showing on when clicked Render

It looks like you still have the default settings in the preferences. You need to update them with valid values.

From that post I linked:
"To configure the Wings3D YafaRay plug-in, you simply Edit > Plug-in Preferences > YafaRay > Browse to the Executable ("C:\YafaRay\bin" folder).

Depending on the version of YafaRay you are using, you may need to add "-pp C:\YafaRay\bin\plugins", without " ", so that YafaRay can find the YafaRay plugin folder. Your path may vary..."

You need to tell where Wings3D will find the yafaray by browsing it until the place you installed yafaray in your hard drive.

Whe you do that, the Render->Yafaray will wor fine.
