Quickly looking at [GitHub - JPF12141999/Toy-Story-2-Ripoff-Game: Ripoff of Toy Story 2: Buzz Lightyear to the Rescue, which takes place in the SpongeBob Universe instead.](https://github.com/JPF12141999/Toy-Story-2-Ripoff-Game) :

1. You placed all files, code and data, at the top-level folder of the application. This makes it hard to see what’s going on. Please move data files to `data/`, code to `code/`, as all CGE examples do and as new CGE projects (created using “New Project” from CGE editor) have.

2. Your code defines `TThirdPersonNav` derived from `TCastleThirdPersonNavigation`, and then `MyThirdPersonNav` derived from `TThirdPersonNav`. This is not necessary. You need only one descendant from `TCastleThirdPersonNavigation`.

3. The `SetAnimation` has to be declared with `override`, right now it obscures the virtual method instead of overriding it. The compiler warns about it:

4. Your design refers to absolute filename that can only work on your system: `file:///C:/Users/Joshua/Downloads/SandyTreedome-zipline.glb` .

I didn’t yet get to actually see the blank screen, so I can’t comment on your exact question. If you fix AD 1 and AD 4 above, I’ll be able to easily test the project on my side.
