* `transparent_portal_surface`
This behavior can be overridden by using the `no_portals` argument. To accept
portals, the geometry must also have associated collision so that it can be hit.
This can be done by placing a coplanar static collision object or through
animation with a [bone](./anim.md) that also animates a dynamic collision
object.

A mesh's UV coordinates are only used if its material does not have the
