Ok so its probably a dumb question but I've been looking for answers but had no luck. I understand that the boxes aren't bones, but is there no actual way/better way to use them on the chart? I'm new to this (who would've guessed) so I don't fully know if i can add these boxes to the frame chart, or I need to do something else.

also if you have a really good video on teaching me everything about MMD, I would love and appreciate it :) (most videos I found are tips and tricks, which are really helpful but i need to learn the foundation of MMD)
