Hi! I want to learn how to develop Scene Kit games. I already know Sprite Kit so I think it will not be too hard. I don't have any experience with 3D objects so I've downloaded some files from the Internet.
Now I have some questions:
When I import .dae (COLLADA) files in XCode they loose their texture. I read on the Internet that these files must be exported with Maya... Is it true? Should I use maya to re-export these files?
What is exactly "Scene graph" and how do I use it to move single parts of the object?
