Can you draw Grease Pencil strokes that snap or align to the perspective of the 3D scene?
This might be similar to how some 2D drawing apps like Procreate allow you to draw lines that align to vanishing points in the scene and this would be used to indicate the perspective and / or eye line of a frame in a 2D/3D hybrid storyboard.
As far as I know you can’t snap grease pencil strokes to the 3d viewport grid, but if you already have a basic stucture made of 3d meshes (a bunch of cubes to represent a city for example), you can snap the grease pencil strokes to the surface of those objects.
Also, since you’re already working inside a 3d environment, there’s no need to fake the perspective like in 2D painting programs, just setup the camera and a couple of primitives (planes, cubes, spheres) how you need them and then draw on top of that.
