The Raycast Raycast Node¶ The Raycast node intersects rays from one geometry onto another. Instead of using the Hit socket from Raycast, you could do a separate Is Inside? check for the spheres, and use that as your multiplier, automatically eliminating hit distances The problem is that the raycast goes from individual points along the source geometry in the ray direction looking for the target geometry. This one is all about the Raycast node. The proposed approach is shifting the Source Position along the Ray Direction such that the new Source Position is on a bounding sphere of the Target Geometry, thus outside of the Target Geometry.
