I decided to try animating using the custom poser feature and the result was:
Go learn Blender, really. I can’t recommend anyone to try animating in WL. The fact that you have to rely on events/functions makes it a mess very quickly and keeping track of everything is just awful. I tried to make something like a keyframe using events, it was a nightmare and made my head hurt.
I'm not saying you can't do it but unless you're a psychopath and enjoy torturing yourself, feel free to try it out, maybe if at some point they add something resembling a graph editor or timelapse feature then maybe it will be easier to animate but other than that stick with Blender.
Also more of a personal opinion, but I really wish they would simplify (or explain better) what specific events/functions do in the sandbox, most of the time I feel lost on what they do or how I make them do the thing that I want. It felt that way when they introduced automation into the sandbox or when they introduced the more complicated ones, I'm probably missing out on something cool I could do, but how the fuck am I supposed to know if, again, most automation stuff is so confusing to use.
