the one above (dave8) is very nice IMVHO.
to ameliorate the GI (IDL) artifacts in syedady's img, try these settings in d3d renderff script:

• irradiance sample size 4 or less
• IDL intensity 0.8 - 0.9
• 16 bounces
• 2048 samples (or more)
• IDL irradiance cache 100.0
• raytrace irradiance cache (red) doesn't matter
• don't use AO
• raytraced shadows
• 16 pixel samples
• 0.1 shading rate

these will cause the render time to increase quite a bit
