First Person Areas
A first person area defines the bounds of where a Desktop user can move. These are similar to a Teleport Area but instead these are only used on desktop.
An example of First Person movement areas colliders being used in a scene (Green)
Setup
Using the SampleModule scene as a basis navigate to Locations → First Person Areas
Restrict Movement Colliders is what powers where the first person avatar can walk.
Position the Walking Mesh child to best fit the environment geometry.
If you wish for more complicated geometry duplicate the child object with the collider for any new movement areas.
Add the new duplicated object to the RestrictMovementColliders → Travel Areas property mentioned in step 2.
Note
Movement areas are very sensitive to changes in elevation, be careful that you do not change the y level of objects when moving them around.
