Greetings to all. In this class,

we will learn how to add colors and materials on the model.

Before we start, we should remember that the orientation of

the faces determine whether we can add colors successfully or not.

Therefore, we should check all the faces in the model are on the front side.

We use a cube to demonstrate how to reverse the face.

Let's get started. First the video shows white side is defined as front sides,

while the grey is the reverse of the white side.

There are two methods for us to reverse the face to the front side.

Method one, click on the face and click right mouse button.

Choose reverse faces.

There we get a reversed face.

Method two, click right mouse button and

one of the front sides and then choose orient faces.

There we can see all the upside faces of

the objects will be oriented to the side of the face.

Let's check the faces in our model.

Remember to reverse all the faces to front side,

otherwise we can have problem when we apply colors or materials on it.

In this class, we learnt how to orient and then change the faces in the model.

Remember that there are two ways to do this,

and we should use the one that fits our situation.

Let's stop for now. Goodbye.
