Adding materials to the walls

To make the ground look more realistic, we will apply a material to it. Go to Content Browser | Content | StarterContent | Materials. Type Wall into the Filters box. Select M_Basic_Wall and drag it onto the surface of the wall with the door. Then, we will use a different material. Type Brick into the Filters box. Select M_Brick_Clay_New to apply to the inner surface of the two other walls.

Here, you can take a look at how the level looks in the Unlit mode after applying the materials mentioned previously:

Build the light before running the level again to see how the level looks now.
