Parent-child heirachies are used in quite a few engines, and in other software. Anything done to the parent will affect the child. For example, if I move an entity, all its children will move, too.

You are absolutely right, too. You posted here in the Future forum, so you weren't looking for alternative solutions to your problems, you wanted Contitec to implement these Blitz3D features for you. Good luck, and I won't reply anymore.
