Multi-texture - 2.49b

Hi,
I have modeled a room. which is a single mesh. Now I want to assign different texture for each face. like floor texture for floor, ceiling texture for ceiling, wall texture for wall etc. How will i do it? I tryed and i can see diffrent texture on each face on viewport but nothing on rendering and pressing P. help please.

Regards

If you want to keep it a single mesh, apply different materials to where you want a different texture. In blender 2.49 you are limited to a maximum 16 materials per object. If this is not enough, split you mesh into separate objects (select the faces you want to split and press P)

Hello,
16 textures per object, it is too much for me. I only need 3 - 4 textures per mesh. it is working now. Thank you for your reply.
