One model - with several textures: howto?

I found it:

it' much more basic really:

just use this:

room = loadmesh("office.b3d")
C_Text = Loadtexture("textures/Room_01_Texture_1024_day.tga")
C_Text2 =LoadTexture("textures/city_day.tga")

entitytexture room, C_Text
entitytexture room, C_Text2,1

the model has a texture for the office scenen and one texture for the bitmap seen thru window..
