Hi, Lukas
If you're confused on how the animate tool works, join the club. I have figured out some of the basics though. I made 2 posts about it with example programs a while ago. So, if you click on my mii picture you should be able to find it.
Hope this helps!
Yeah the manual says you can use the tool to make adjustments to animation data. I'm guessing its a more physical approach rather than dealing with numbers. But yea I don't get how it works either.
