Collision detection model at the wrong position #18182

Category: Physics

%%%Tested on Linux and Windows.

The collision detection model does not match the object orientation and position located in a multi level tree. It match only for the first level using the compoung option.

Ex:
Parent
+----child(match 1st level
+----child (match 1st level)

   +-------------child (no match 2n level and deeper)

The rotation matrix and position vector should be apply in all nodes of the tree recursively.

See the image attached.%%%

%%%A few things that might help to know. Is this with 2.48a? There have been quite a few physics changes in the SVN, so I don't know if this may already be address. Also, are there any armatures/bones in there? The physics sometimes doesn't play nice with those.%%%

I tested on linux and windows with the 2.48a. I didn't try with the SVN.

No bone.%%%

Is this still a problem? If so, please provide a sample file demonstrating the issue.
