How can I connect different geometry collections using a proximity?

I want to connect geometry collections placed within a world or blueprint using distance, but how can I connect different GC assets?

The dataflow has a Proximity node, but it seems to only work within geometry collections.

Basically, I want them to be completely glued together and behave as if they were a single geometry collection.

Previously, Cluster Union or Cluster Group seemed promising, but they stopped responding to line tracing, so I’m exploring whether the same thing can be achieved with Proximity.

Cluster union or cluster groups are meant for that
There’s was some issue at one point with traces , but they got fixed in some recent 5.7 hot fixes

I’d recommend giving them a test again and report if you still have any problem with them
