Moon animator animating parts & rigs

I’m using Moon Animator, but I’m confused on how to do an animation properly.

I know how to animate rigs, but I’ve added parts on the rig and want to animate them too.

I make an animation, but it converts it to a Moon 2 File which is useless to me and I can’t upload it to Roblox.

I tried to export Rigs and it would put the animation in AnimSaves, however parts aren’t animated then…
