Hello! I have a problem with using map made in Blender. Everything is working when I am using a map made out of just one plane with textures. But when I use this one, which consists of different objects and multiple textures, it shows a this._world is undefined error. Everything works just fine when using Sandbox. I really don`t understand what is the problem.
