Update the glb import to apply the desired materials at import-phase
Simplify teleporter disabling by setting the process mode to PROCESS_MODE_DISABLED
The PROCESS_MODE_DISABLED trick works because the StaticBody3D nodes have their disable mode set to "Remove".
Note: configurable materials (the transporter effect and title) still need to be set in "Surface Material Override" as this lets them be marked as local-to-scene so they can have individual shader properties.
