The light path node is a node that we can use when creating materials for Cycles or Eevee in Blender. This is the seven first inputs in the node. I have limited this article to only discuss the different ray types and corresponding outputs on the light path node. The light path node allow us to access this data and manipulate our material based on these ray types. As these rays bounce around in our scene, they get tagged as different types of rays. What is the light path node in Blender? As we render, rays are cast into our 3D scene from the camera. Hopefully, this article can help you learn what I learned about the light path node quicker. To finally demystify it, I studied it a bit to learn how it works.

While I have found it useful, many times I have not fully understood what it does or how it does it.

The light path node in Blender has always been mysterious to me.
