I'm having trouble implementing a starter character. Now it's a rectangle but I did make it out of separate parts like Head Torso HumanoidRootPart etc just so the scripts that wait for those could still run normally. when adding a humanoid it seems to try and round out the pieces and shape it differently. What I really want is for this rectangle to smoothly move along the ground and not rotate the way a player does as my end goal is to use it basically as a hitbox for the player.
Ah, those are bevels, and to my knowledge, you can't remove them. However, in your StarterCharacter, you can make the torso, head, and limbs transparent and WeldConstraint or Motor6D your new parts to the old ones, just make sure to rename them.
