Can you please explain exactly what you are trying to do in this entire block of code?

I’m starting to get [REDACTED] because of people NOT FORMATTING THEIR CODE. (Even though Roblox added this feature.) And it’s quite obvious this is not the whole script.

But, what I suppose is that the Raycast is hitting something very next to it’s origin. I’m not sure if filtering descendants make it so Raycasts can’t hit the filtered 3D Rendered Instances, but I rather suppose that it just makes it so the filtered descendants, even if hit, are ignored.
