Summary
Setting the Cluster Group Index of a Geometry Collection to a value other than 0 will cause line tracing to be ignored.
Similarly, if you specify a bone ID in Cluster Union, line tracing will not respond to bones other than the specified one.
However, in both cases, they do seem to respond to physical collision.
I think both are probably set up using the same logic, and it’s just a bug that occurred due to an oversight.
I’m not sure if this is reproducible, but I’ll report it as a bug.
