So what I got from this is you did a shit rig and want someone to do it for you and then send you the rigged model. You also include the skin to "your roblox model" then tell people not to "steal" the skin when this is a public skin and once you upload this it is then for public use. Correct me if I'm wrong here...
Just thought I'd put this out there, this is showing as just a file once downloaded, can't open in unity or blender, any chance this can be converted to a unity package so it can be used?
