Does the issue occur in the editor or during gameplay? If it occurs during gameplay, please specify which movement system is being used (free movement or grid movement):
Gameplay (Grid)

Briefly describe the issue you're experiencing:
When starting the game the main menu and when you enter the game, it is displaying the indiviual shapes outlines of the 3D voxels.

Are there any errors in the in-game debug console or external console window?

ERROR: SelfList<class GDScriptFunction>::List::List: Condition ' _first != 0 ' is true.
ERROR: SelfList<class GDScript>::List::List: Condition ' _first != 0 ' is true.
ERROR: ResourceCache::clear: Resources Still in use at Exit!
ERROR: There are still MemoryPool allocs in use at exit!
ERROR: Reference to a Thread object object was lost while the thread is still running...

Provide the steps necessary to reproduce the issue:

Make a simple small map to use with along with Slayer's Custom Menu tutorial part I
Place Character's that have animations with different colors
Save the map as the Menu BG so that when you load the map, it will show characters moving in the background
then launch the game.
