Pencil+ 4 Maya - Render Elements Problem


I recently got Pencil+ 4 for Maya, and am having a lot of difficulty figuring out the basics, as the tutorials are either blurry, too fast, for 3DS Max, or simply not the topic I’m looking for.

What I want is (should be) pretty simple, actually.

I want to render my lines separate from the geometry. I’d like to render the geo with lighting as a separate layer, if possible. But black lines separated from the background is totally okay, as well.

Every time I click Render Elements, the lines disappear. If I uncheck it, they show up, but then it’s a merged image, which doesn’t help me. I’ve played around with all of the settings I can imagine, to no avail.

Does anyone have step-by-step instructions on how this can be done?
