texturing both sides of walls differently

i am in a class that is designing building in blender.
i would like to texture the inside side of the wall differently then the outside side of the wall. is there anyway to do this??

i’m a noob.

thank you.

Check out “Material Indices”,
That should tell you everything you need to know, past that, it’s simply a matter of setting up 2 materials with different textures and setting them to the different faces.

The wall will have to have a thickness, you can’t have 2 materials on opposite sides of the same face.

thank you. it helped me figure it out.
