Hello,
There’s an experimental feature, “Actor Sequence Editor” that might help in your case. Enable it in Plugins->Editor->Actor Sequence Editor.
Once you have that, Add an Actor Sequence using “+Add Component”. From there, you can add components from your blueprint and animate them. You can also playback settings on that actor sequence, like autoplay, loop, etc. Then add your blueprint to the level and hit play. Here’s what I have set up to have a cube moving up and down in a blueprint.
Keep in mind this is an Experimental feature and is subject to change…
