I created a swing door which had a collision mesh as a child. This works well and blocks player when closed and allows through when open. I have now created a sliding door using the same technique but in T3D the collision mesh does not move with the door. I read that this works if you put a bounding box around it but I tried that and things remained the same. I know that there is a door resource somewhere but I would like to do this without c++ changes.
If I view it in the T3d editor and show the collsion mesh it does move with the doors as can be seen in the image. However in the mission you can see in the middle a white square which seems to be the collision mesh. If I turn off collision then the player can pass through.
