# Adding New Surfaces ( Grounds )

Setting the ground properly in FPS Engine is essential to inform the Player about which surfaces are walkable and which are not. Fortunately, this process is quite straightforward.

* On your surface, ensure it has got a Collider assigned.

{% hint style="info" %}
It's advisable to avoid using Mesh Colliders whenever possible, as other collider options offer more precision. If you must use a Mesh Collider, Convex Colliders generally provide better results.
{% endhint %}

* Attach the Ground Physics Material to the collider
* Assign one of the provided Ground layers to this object (e.g., Ground, Mud, Grass, etc.). 

{% hint style="info" %}
This step ( Adding the layer ) is not necessary on 1.3 or above for the ground to be detected as walkable.
