Sorry 3D-Mobster, but that setup doesn't work for me.

I set my gamma correction back to 2.20 (Which, as some experts always insisted, is the physically "correct" value and is what Poser uses as its default)

Used only one point light with the settings you suggested. (Size 1500%, intensity 950%)

This, after a few attempts, is the result:

Don't like it, sorry.

But the biggest issue is that now my preview is completely messed up because the OpenGL can't handle the point light shadows as nicely as it works with infinite lights.

And as I spend 99% of my time staring at my scenes in preview mode, a "nice" preview is very important for me.

Now back to Gamma 3.50 and my infinite lights setup:

Here's the final render:

And here is my preview:

It not only gives me immediate visual feedback for my scene, it IMO is "nice enough", you could probably even use it for a real time animation.

I don't doubt that your way is the more physically correct way. Believe me I spent hundreds of hours experimenting with various light setups, trying to follow the "physically correct" Poser gurus.

But in the end I made my peace with the fact that Poser is just a hobbyist app and was never ment to be "physically correct" in the first place.

So instead of forcing it into a certain direction, I just allowed it to show me what it actually can do.

That made my workflow a lot more pleasant.

Still, thanks for taking the time and trying to help.
