Hi i went through the tutorials at this link
mesh Imesh IImesh IIIthey cover the basics of how to make a symettical modely ironically a lighthouse something I wanted to reproduce in mesh that i have in sculpty form now
however its missing the part with the "how do you add textures" so I will make a video/videos on the missing bits and then make the initial videos later since well an example already exists so stay tunned for "how to texture your objects" and UV mapping in opensim which once you learn it you will never want to use sculpties again lol
