Subject: Make prop invisible but still blocking light?

If I'm prepping a scene for later compositing PhotoShop, I'd like to be able to turn off the props for some shots but not change the lighting in those shots. In other words, when the props are invisible, light comes through and illuminates the figure full force. In the original base scene, some of the light is blocked. So the later, overlit renders look "pasted on" when layered onto the original scene with its original lighting and shadows. Any way around this in Poser? Make the light-blocking elements invisible while still blocking light?

I think you can make an object invisible and still have it case shadows.

Where do you do that, Laurie? The "Cast Shadows" setting in Properties doesn't seem to have any effect when the object is invisible.

Oh, it doesn't? Aw, that blows :(. That's what I was thinking of. Crappers.

I thought if it was not visible... it was just out of the way and "left" out of system resourses. I didn't know you could alter it's properties if it's invisible.

It would be a lot of work,you'd have to export everything as .obj, convert to povray with Poseray, render in povray with the no_image, then render just those elements you didn't want the image and layer them together.  Second render would be with the no_shadow, obviously.  But you'd have to export anything you wanted no-image as a separate .obj, time consuming to say the least.

You just uncheck "visible in camera" on object.

It will still block light and cast shadow but not show when rendered

Medzinator, thank you!

How did people composite scenes before "Visible in Camera"? Fiddle the lighting and shadows in postwork? I guess they could have rendered just the shadows, then rendered the objects they wanted, separately, without shadows. But that seems clunky. The camera thing sounds ideal if it works, I can't wait to try it.
