Custom board specification
Refer to this page if you want to make a completely new board from scratch,
otherwise use the template file.
The board system looks for marker entities. These can be applied using the entity tab in the skaterift exporter panel.
The aliases used for the marker meshes:
 wheel (x4)
 truck (x2)
The scale of each part should be [ 1, 1, 1] and have no rotation.
Origins should be correctly placed at the place where the items are joined to eachother, refer to the diagram for the placement and size.
