I’m dealing with an interesting challenge. Basically, I’d like to light my scene in a pixel art fashion (except in 3D, so I guess that would be in a "voxel" fashion).
I initially wrote a wall of text, but I've decided instead to make a few renders to better illustrate what I'd like to achieve.
First, this is my setup (viewport screenshot):
Now, a traditional way to light this scene would be to use a Spotlight, as such:

But this is not the result I want.
I would like to find a way to light my scene/meshes in a way that resembles this:

Problem: The method I used to create the render above is utterly inefficient and CPU-intensive. In short, I'm duplicating each voxel of the bicycle, extruding those duplicates on the Z-axis and detecting any intersection between those extrusions and the "wall". See here (in red):

Objective: I would like to find an efficient way of having the boundaries of the lights/shadows projected onto my meshes to be restricted to the voxels/cubes they (those same meshes) are made of, i.e. in a pixel art fashion.
I've attached the demo scene to this post.At this point in time, I’m wondering if this is even possible to do with Octane, or Cinema 4D for that matter (unless I decide to dive into Python or something). That said, given my novice status, there could be a ridiculously obvious solution that I haven't thought of. I feel like this could be more likely...
Any advice/tip/insight would be hugely appreciated. Seriously. Even just keywords to Google, etc.
Thanks a ton!
