Quote - Tips when using Pose2Lux (that I've noticed): When using outdoor lighting, use an infinite for a sun and diffuse IBL for the sky. You can then balance the direct light from the sun with the ambient light from the sky easier in Luxrender.

Emitters make softer shadows than actual lights. I'm not sure why this is, just that it is ;o).

Not sure if you've taken a different stance on this yet, but if you haven't: what are your settings for these lights? I have this image which rendered thus in Poser:

which I exported via Pose2Lux (lights and all)... so lights were 1 inf at 120% and 1 ibl at 12%. In P2L, I set the Inf as sun and IBL as sky. Get all this into Lux, and start rendering:

So, I'm doing something massively wrong. Settings in Lux:

Sensitivity: 64
Exposure:1/250
FStop:5.6
Gamma:2.2

Light groups:
Sky Gain: .05
Sun Gain:0.2
