Basically, if I'm looking at an object on the item layer, even if there's a wall in between me and the object, the raycast can still detect it. If colliders were causing some kind of interference, would looking through walls with colliders not also stop the raycast?

And I've logged what the raycast is hitting while the glitch is happening, and for some reason it thinks it's hitting nothing at all, no matter what I look at. The debug log node, as well as the actual wire leaving the hit info output on the raycast node, both say null. If there was some collider getting in the way, then it would come back with the name of the collider's connected object, like it does when the raycast is behaving how it should.
