I can't see from your posted image why you would need 100 groups. It looks like you probably need 2-3 groups to handle the terrain layers (but depth buffer would work fine here), and another 2-3 groups for the foreground objects. Is there any particular reason I am missing as to why you need so many? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pyglet-users" group.
