Umm, so let me get this straight, you want someone to walk you through how to replicate something you can buy on the market so you don’t have to pay? That’s pretty messed up. And I don’t know anyone that’s going to do that for you. That is 3D modeling, texturing AND scripting logic. I would have helped you script the logic as you can see I created a fully functioning elevator for you. But if you want a “polished” look that’s something you’re either going to have to purchase or create yourself. Definitely well beyond the scope of an answer hub question. Your question made it seem like you didn’t know how to create the functionality of a basic elevator system and your only option was the market place. That you would have absolutely gotten help with. This however is not something I can or would help you with… sorry.
