My goal is to have a wall off in the distance a little bit, and when the player looks at it, parts of it fall off. I have already cut the wall into the parts that need to fall off but I don't know how to make them do so.

Any help is greatly appreciated.

thanks

Make all the bits of wall that you want to fall of separate brushes and then tie them to a func_physbox, and name them all the same.

Set the flag 'Motion Disabled' on them all.

Then use a trigger_look to set the 'EnableMotion' output and gravity should make them fall.

Rob.

one problem though; some of the func_physboxes fall inwards instead of outwards, which is right onto a surface that needs to have a portal on it.
How do i fix this?

Can't you simply protect that area (direction) using a func_clip_vphysics or a temporarily trigger_push?
