Improving edges with texture painting

We will now learn how to use texture painting to improve our material by painting over its edges. We will use a simple cube to demonstrate this technique, but you can apply it to any model or texture. In the following steps, we will shade the edges of our cube:

1. First, add some loop cuts near the edges and smooth shading to the cube to make the edges appear smoother, as shown in Figure 9.10.

The loop cuts will automatically be added to the UV map.

2. Open the Color menu in the Image Editor and select the Eyedropper tool, as shown in Figure 9.11.

Then, click on the dark image texture to copy its color.

3. Increase the Value setting by approximately 0.015, as shown in Figure 9.12.

   This slight increase in brightness will allow us to lightly shade the edges.
