  Himy problem is that i draw a room with 3dsmax 9 and i export it with FBX extention, import it to my game and what i see is that all the meshes has been centred and not well positioned like from the originale.so here is a pic of my model from 3dsmax :http://m-ug.freehostia.com/tmp_img/img1.jpgAnd when executed with c# i get that:http://m-ug.freehostia.com/tmp_img/img2.jpgso after searching i find that i must Attache them to each other, like that:http://m-ug.freehostia.com/tmp_img/img3.jpgAnd i chosed the first option and got that:http://m-ug.freehostia.com/tmp_img/img4.jpgSo i tryed the second "attached" option and i got :http://m-ug.freehostia.com/tmp_img/img5.jpgthe textures has been reversed ?!! i don't want to make the postion of every mesh by code,i want to importe all the room in one piece and must be positioned like shown in 3dsmax, so how to do so ?thanx from your answers
