A little trick that worked for me after LadyRaine told me:-

Get your lights set up, for the Resident one, I used 2 lights, a lightmesh and the sunlight mesh.

For the lightmesh, I used the Point at option for Objects in Poser, and pointed at V4 body.

Then I let Reality do it's bit to export to Lux.

Once it started to render I changed the Tone Mapping from Reinhard-non Linear  to Linear, then click on the Estimate button.

Go down to the Gamma + Film Response section, and then change the settings to the various film options to experiment.

Go into the Lights option and change the gain if required.

Let Reality do it's thing.

I hope this has been of use.

All the best.
