im currently creating a deformer for personal use in order to equip a custom robot avatar. i have created a series of deformers for each limb, but every time i apply the deformer to the legs, instead of the avatar getting taller the feet start to pass through the floor. i'm very aware that you can get very large avatars so i would like to know how you keep the avatars feet firmly on the ground and not passing below it at all times. is there an offset i have to edit? thanks!! /ok i fixed my first issue by using an animation to lift it off the ground, but now when standing, the knees bend awkwardly and the feet actually lift off of the ground, is there any good way to make a large avatar :s the knees only bend when standing on actual ground, when i stand on a prim its fine.
