How to pose with a skeleton?

So, I opened the default character’s skeleton file, and I maange to position it’s hands in a position I like, and I clicked Save. How do I go about spawning the character in that pose?

Under the Animation properties of your character, you should be able to select your pose assuming you saved it out as an animation or such. Eventually you’ll probably want to setup an animation blueprint and/or state machine so you can blend in and out of that pose and into various other animations.
