Let's build a scene with some slopes, like this:

Figure 8.8 – Scene with slopes-NavMesh02-Slope.scene

One important thing to note is that the slopes and the wall should be in contact. If we want to use NavMeshes, objects need to be perfectly connected. Otherwise, there'll be gaps in the NavMesh, and the Agents will not be able to find the path anymore. There's a feature called Off Mesh Link generation to solve similar problems, but we will look at Off Mesh Links in the Using Off Mesh Links section later in this chapter. For now, let's concentrate on building the slope:

2. We can adjust the Max Slope property in the Navigation window's Bake tab according to the level of slope in our scenes that we want to allow the Agents to travel. We'll use 45 degrees here. If your slopes...
