Son of a mother f**ker. Days later, I STILL can’t even get started with the most basic and streamlined aspects of UE5, jesus.
After uninstalling and reinstalling UE5, I still cannot set the parent control in the default Stack O Bot sample file. I get a popup screen that quickly flickers on and off 12 times a second or something like that. When I try to set the parent control of the Antennae of the Stack O Bot to anything, anything at all, the rig forces me to choose nothing. Nothing happens, no new parenting, the engine forces the parent to stay as nothing.
Professional tip: do not hire people to put in charge of your operation simply because they have a business degree, they do not generally have industry-specific experience needed to sustain long-term development. Hire actual scientists and actual designers who have actual experience and real-world economic knowledge.
