Are you placing the thing in a way that it blocks the hatch? If yes, that's your problem. >Boamere What does the log say about it? >montyben101 Umh... can you be a bit more specific about this? >Justin Kerbice Well, the module is not intended for loop animations. However, you can create a loop anim and then another one which animates the loop animation's parameters to make it start/stop. The only problem whould be that the rotated object's position whould not be kept during save/load cycles, but that shouldn't be much of an issue in most cases. Sorry that it took a bit long for me to reply, I was a mix of lazy, ill, and not at home.
