Collision boxes revisited

Hi all,

I have been trying to get collision boxes to work but so far I have had no luck at all. I'm currently using blender and exporter 0.96. the way that I'm creating the shapes is by the following process.
1. create a mesh (a simple box)
2. create 2 empty objects call one shape call the other Detail32
3. link the cube with the empty object called shape (shape is now the parent of the cube)
4. link the empty object called shape with the empty object called Detail32 (Detail32 is now the parent of shape)
5. create another cube and call it mesh
6. create an empty object for the collision mesh and call it Col0
7. make Col0 the parent of mesh (the collision box)
8. link the Col0 empty object to Detail32
9. save the file
10. do a quick export

When I place the box in the mission all i see is the X,Z and Y arrows and no box. Am I doing something wrong, Maybe the problem lies in my setup of the object hierarchy in blender.

Does anyone have any ideas because I'm stumped.

I did go to outliner and didn't see anything displayed in there which may mean that for some reason its not exporting my scene.
Oh by the way there is no animation in my scene its just a simple box, if that helps anyone.

As usual any help would be greatly appreciated

Cheers

Chris
