CS and CEL use a technique to test CD only with objects that are near. 
To test if
two objects are near CS will compute the distance between the 0,0,0 points
of the objects. This is also the case for lighting. So it is always 
recommended to
place the 0,0,0 point of the object at a suitable place in the object 
and not
removed from it.

I don't understand this. What do you mean by 'modifications in Blender'? 
What kind
of modifications?

CS should do the lighting. So you must add some lights and
do -relight on the level.
