Transit must add a new platform-bench prototype to a station pointInstancer without rebuilding the whole station scene. What should authors do?
Select an answer to reveal the explanation.
Short Explanation
You can add a new bench style to the instancer’s prototype list without tearing down the station—like adding a new stamp without reprinting the whole map. Hook instance indices to the new prototype where those benches belong. Rebuild-the-world is the expensive wrong turn.
Full Explanation
Transit can add a new platform-bench prototype to a station pointInstancer without rebuilding the whole station by authoring an additional prototype and wiring new or updated instance indices to that prototype. Extending civic instancers is an incremental aggregation task: grow the prototype list, then map instances that should use the new bench. The station assembly and other prototypes remain intact, which is the point of pointInstancer content aggregation for platform furniture.
Flattening the station to USDA text and hand-editing every world transform into unique prims is the expensive wrong turn for a municipal twin. Muting all existing prototypes so only cameras remain does not add benches and blinds the station. Converting the pointInstancer into a single Mesh prim named Bench collapses aggregation and loses multi-instance authoring across the platform.
Exam caveat: new instances also need transforms (and any other per-instance arrays) authored in parallel with protoIndices—prototype alone is not enough. Operational check: add the bench prototype, append or update instance arrays for the new seats, recompose the station, and confirm benches appear at intended poses without unique-prim explosion. Spot-check that existing prototypes still index correctly after list growth so prior platform furniture is not remapped by accident.
