I was working on my laptop in a doctor’s waiting room the other day, twiddling with the construction script of a Blueprint, when my trackball sort of slipped. Next thing I see is a completely empty construction script gaph, missing its root node. I could still move around drag other nodes in, but without the root node I had nothing to connect them to.
A quick Google search revealed that this has happened to folks regularly since 2016, and there’s seemingly no easy way to focus on that root node from the menu (assuming it isn’t completely gone, which would be a serious bug). The most likely scenario is that it’s been moved away so much we just can’t see it anymore.
Here’s the solution that worked for me:
- select everything in the node graph with CTRL+A
- now press the HOME key to bring everything into view
This will reveal all nodes – no matter how far zoomed out and spread out they might be. Two new handy shortcuts that I didn’t know about! I had previously assumed F would focus us in on a selected node like it does in the viewport, but of course that’s not how it works. Logic and 3D applications cannot exist in the same universe at the same time.
Thanks to ixicalibur for this simple yet effective solution!
