Quote - nyght, I dunno if this helps, but poser has the shadowcams for directional lites.  I haven't tried D|S yet.

I'm familiar with Poser's Shadow Lite cams.  Their functionality pales in comparison to what I can do with Studio's camera lights.

I use a 3D mouse for both programs - the Space Navigator by 3D Connexion.  In Studio, I can select the camera light for any spot or infinite light in my scene and then use my mouse to "fly" the light to whatever position I want, even rotate and spin it around.  I can't do that in Poser.  I have to use the parameter dials.

I've recorded a couple of short videos to demonstrate.

This is a Spot Light cam in Studio:

And this is a Distant Light cam in Studio:

Good question.  I might go ahead and download it just to find out.
