Access to hidden layers in scenes

Has access to scene properties (other than camera) in the SDK been permanently deprecated? I need access to the hidden layers in particular.

I know nothing about the SDK, and precious little about Ruby. But I’m starting to recognize common terminology, and this MIGHT help with your problem:

“Geometry” can be hidden. “Layers” not so much. Since layers are for visibility purposes ONLY, the property of layers is either visible or invisible (I didn’t quote those since I’m not sure how the SDK or Ruby might call this property.)

Since Layer visibility is NOT the same concept as “hidden” Geometry, is it possible that you’re simply looking for a non-existent setting? And that you should be looking for something related to visible/not visible?
