I explain my dilemna, i try to tell to MMF2 to replacing OVER a SIMPLE backdrop my object.
It's an Active Object.
So, i want replace this object JUST over the backdrop object, for that, i had the idea of respositionning the "POSITION" of the object by the "Position of the "HEIGHT" of the object..
But, i'm afraid because i have NOT the possibility via MMF2 of knowing the height of my object, because, MMF2 do not support that parameter..
How i can make that please guys?
