Thanks @Liebranca!
Are you sure that there is no way around that? I was hoping to achieve this by standard (non-Python, Logic Bricks) means. Not because I am afraid of it, but it feels overcomplicated, as the Action Actuator has everything needed in place…
Nevertheless, I’ll give libLoad a try.
Edit: I added what you suggested in other thread, but loading animation via libload somewhat feels clumsy compared to the action actuator.
