I added a loader to increase performance also its not like other loaders when they just go through the costumes it actually forces scratch to load everything. so you might notice lag spikes when the loader loads every costume this also reveals a very big syncing issue with the animation when some parts are way to long and it makes the animation out of sync they were prob working with the lag.
I'm maybe making this more automated in the future. cause it does requiree alot of coding on your own to add it to your project.
