I am trying to build an app where a user is given a human model and he/she can move the model and give it a difference appearance (e.g. changing the color of the cloth, hairstyle etc). The change will be saved into the Bubble database and retrieved. I have done some preliminary search on incorporating WebGL, OpenGL or Unity 3D but have not got a clear idea of how to embed these assets into the Bubble app. Any idea?
