uvw map

Hi I am tryng to map in GAMX 1.2 a fuselage but I get stuck on the method .because in FS it show only one of the uvw map applied to my fuse.My fuselage it's one mesh polygon, I created one texture one for the left and one for the right of 1024*1024 I see the wireframe to fit the mesh .I create a multimaterial with 4 ID and put on slot the left texture and the right texture.The id 1 and 3 are left texture and ID 2 and 4 right textureI start working on using mesh select and selecting a portin of polygon, let's say Left front, with selected polygon I chose UVWmap and fit the gizmo portion with my texture and give the correspond ID on mesh select.I use the same method the back left of my fuse, the right front and the back right.When I finally export i get only one uvw map applied to my fuse.Where I get lost I don't know but maybe this is not the correct method.thankSimbio
