Feral Heart

Hey guys, I'm new to FH, only been playing for a day, and I wanted to ask a few questions involving presets. If I create one, can other players not see me using it? And if not, is it possible to somehow use a preset as a template for a character, and then 'turn the preset off' or something? What I mean is, if I used  the material files from someone else's preset, would other players see this, or would they simply see a white lion/wolf? And if they could not, is there any way to make it so that they CAN?

Thanks!
