I'm pretty new to Blender so I'm testing out its different capabilities, particularly in Grease Pencil mode, but I've found myself stuck and would appreciate some help.
The link above shows my issue. I'm working in Blender Grease Pencil 2.8, and while I've figured out a decent way to use a 3D mesh object as a reference to draw stroke lines over (first half of the video), I can't figure out how to have my 2D animation, the stroke lines, on TOP of the 3D object (from the camera's viewpoint), as if the ball were bouncing up the 3D mesh. Instead, the planes of the drawings are slicing THROUGH the mesh, when I just want them to be the top "layer," if that makes sense. Since the 3D stairs are not a stroke layer, I can't just place it below the strokes, and I've tried moving the 2D animation closer to the camera itself but that screws up everything, in regards to camera movement and angles of the stroke planes. There must be a simpler way of accomplishing this than just compositing two separate renders, one of the stairs and one of the strokes, but I don't know how. Any tips or solutions would be greatly appreciated!
(I tried to search for an existing topic about this but couldn't find it, so apologies if this has been asked before.)
