Effect Boxes don't match the lamp models


I'm having trouble with airport lighting recently.

Let me get this straight, First,the models and the attatchpoints are exactly aligned in 3DS Max.

Second as I exported them separatedly, drop them into MCX, and both did FSX earth curve correction.

Then I placed them both with the same reference coordination.

As you can see ,the lamps and the effect boxes are deviated. But some of them are aligned , so weird...



My version of MCX is 1.4, modeling with 3DS MAX including a P3D V4.2 SDK.

I'm looking for a solution for this , wish you guys could help me with it .

Best Regards,
