I'm trying to the Atmosphere in P5 to create a gentle, atmospheric glow eminating from behind a figure in a closed room, but am having no luck so far. I've tried it with a spot (at ~ .025)and with an infinite light (set at very low density ~.003. I've tried just about every combination of settings. Anyone have any suggestions?

good question. I'd like to know too.

Here's the scene I'm working on. I'd like to somehow gently illuminate an atmospheric glow behind her.

Cheat!

Use a semi-transparent sphere prop for a basic oval-shaped light blob, or, for stills, a transmapped square prop to silhouette the figure's outline. -or try both together.

My guess is that your spot is set too low. Start at 100% and adjust down. Also be sure you have your render settings set properly. I've used Nerd3D's tutorial with a good degree of success.

That atmosphere stuff does work, but is fiddly. Disable visibility on your model and back wall and then experiment with spotlights etc to get it working. Another trick is to use a background colour of whatever glow colour you want, and then make the wall and floor progressively more transparent. If you map the V variable into the floor transparency, it will gradually allow more background colour thru as it goes back away from the camera.
