How about setting the size of the stars and the amount of layers? Say I want less layers, would that ease up on performance?
EDIT2: Very strange. When I load the 2D Starfield & the 2D Shape Starfield together, run the game in cocoonJS, 2D starfield works without an error but when I delete 2D shape starfield as a plugin from the project, 2D starfield doesn't work. I can even remove it from the layout and just keep it as a plugin and it works. Cool
