Thank you.
Is that possible to make that request somewhere?
It would be very useful to store all Hud/skyboxes scenes in a dedicated .blend, and load it at runtime.
Now we need 3 actuators if we need 3 different background/overlay scenes (sky, clouds, hud) :
1 actuator that is set 3 times with Python isn’t enough, because it just sets one background scene 3 times.
