Unity Physics: Terrain Colliders

If outdoor scenes are your thing, you will most likely be working with terrains at some point. Let’s take a quick look at using terrain colliders.

The main thing about the terrain collider, is making sure it has the correct terrain data assigned in the inspector.

It’s best to leave objects size at their original 1 to 1 value for the most realistic physics simulation. When it comes to shrinking down your massive default terrain, the Mesh Resolution in the inspector is where you want to make adjustments. The Terrain Width and Height are what you need here for resizing your terrain.

The above window can be found in the Terrain Settings button here.

If you want a more in-depth walkthrough of Unity’s terrain tools, I have a three part article series below. This series covers editing your terrain mesh, texture painting, wind zones, water and foliage painting.
