I have an idea for a 2D game that uses 3D models that are cut at the center of the Z axis. However, I have found no way to properly get just the intersection to show.
Culling the front and back of the camera to be extremely thin leaves a small outline of the model, since there's no way for it to render the inside. I could use ray marching, but it would limit me to primitive objects and seems a little overkill for what I need. I've found a lot of cross-section shaders online, but they require the back of the camera to not be culled.
Below is a visual example of what I need (demonstrated with Blender's boolean tool rather than a shader), any help is appreciated as I've been looking for a way to do this for months.
