Not true. There is no functional difference between a key pressed event and an action event. They only fire once.
I followed a tutorial on this method but it didn’t help.
I also haven’t noticed a difference in play back using the default or a custom slot. “Default” is just a name. But I did find a correlation with selecting previewed sections. In this case, I don’t have any sections. I can try adding them back though. However, another tutorial I followed didn’t and it worked fine for him. He also didn’t use a do once node.
I actually followed this tutorial on that: https://www.youtube.com/watch?v=8CA4e818erY and ran into the issue I am having. I’ve tried different models, and different animations. So you’re right about something maybe being off in the setup.
