Rendering items invisible?

Deke

Is there a way to keep an item in a scene so that light bounces of it, but not have that item visible in a render? I'd like to render a figure while keeping the shadows cast from a wall behind the figure...but I don't want to render the wall. I'd like to keep the figure clean for post comping.

Not exactly for the case you mentioned, but as an option, you could use some shadow catchers in Iray. https://www.daz3d.com/iray-hdri-toolkit

Note that in general, this is done via the Iray Matte option added by the "Create Advanced Iray Node Properties" script included by default, but this is not to say the presets aren't useful to some.

Enable Iray Matt option with 'old ghost light' has already gone. It's invalid with the latest Nvidia driver. The latest scripts for PB version is in here - :https://www.daz3d.com/forums/discussion/609556/creating-a-ghost-light-daz-studio-4-21-1-26#latest

But it won't work for OP's case with iray engine, as the shadow will be gone as well.
