I tested you script and it works great. But i have a few question about it? You have to press E in order to climb up and down but i don't see in the scenegraph if a key press do something. So is it's setup in the script? Can it be change from proximty to climb instead of key press do something?
First I am not selling 3D model or distributing 3D model. If you notice it's a review of apk file of environment work created on Coppercube. Before you say authorize means distributing 3D models, if you download the file you would not see any 3D model files. But thank you for your comment.
