Help wanted with Dynamic prop

ok thanks to some help in the mapping section, I managed to get my cellar door model to appear in HL2. Though now its physics don’t want to update when it plays the opening animation.

Here’s a picture of the problem:

As you can see here, the model’s physics didn’t update to the open position,thus allowing me to place another model right inside the door, but not in the doorway.

If you think you can help, let me know and I can send you the files.

Only way I can think of is make it a jointed collision model and rig the door collision to the same bone that opens the door in the first place

You know, I thought I did that already, maybe I need to re-export.

Or maybe I need to define hit boxes.

Well, it looks like defining hitboxes worked.
