My first modular set

So I’ve decided to have a go at making prefabs with blueprints, which seems like a good way to go.

My method is to assemble my prefabs in the viewport, then convert them to an actor blueprint.

A problem I’m encountering by doing this is that the pivot on the blueprint appears to be random. Sometimes it isn’t even aligned to the grid. :frowning:

Is there any way to adjust the pivot of the blueprint? Or at the very least, snap it back to the grid?
Thanks.
