Character creator is probably the best one out there. The only alternative I’ve used didn’t have the ability to change the rotation of the joints, which made it useless.
The HipHeight of the Humanoid also needs to be modified (as the character will float above/sink into the ground if the HipHeight is set wrong). It won’t happen if your legs have CanCollide set to true, however it’s not recommended as it will mess up your physics.
There are a lot of other things you need to consider when making a character (at least if you want it to be supported by the Roblox character core scripts). All the joints and parts need to be named and parented correctly, etc. In a studio test you can use your character model as a reference for how things should be set up.
