# Scenes & Layers

### Player Spawn

In HoloFair, the Player Controller starts off at origin point (0,0,0) and faces the global forward vector. See the image below and note the orientation of the scene:

![Currently selected gameObject is shown in the inspector. As you can see scene direction is set in way that when users appear in the scene their camera will face forward.](/files/oFSzJLlkdEsW7C6O8JfB)

To have a clearer view of this point for your own scene, you can create a GameObject to see this point and work your scene around that.

### Layers

HoloFair Player Controller is based on RigidBody controller and collides with everything, however movement possible only on layers number 3 and 6. So, make sure walkable colliders are on those layers.

### Scene Loading

Next is about defining triggers boundaries and shapes which will act as portals that will trigger scene loading. HoloFair in general loads scene **additively** in **queue** manner, i.e. whatever first scene user triggered in, the same order they will appear on top of already loaded scenes. The same HoloFair does when user triggered scene unloading. \
More on how to set them up explore the next page about Portals.
