Hvad er PTMD-filformatet?
En .ptmd-fil er en Polytoria Model. Polytoria er en online, blokbaseret sandkasse, hvor spillere bygger og deler deres egne 3D-spil, og denne fil gemmer en enkelt genanvendelig model lavet i Polytoria Creator, platformens byggeværktøj.
Inden i en .ptmd-fil findes et objekthierarki: en gruppe af dele og underobjekter, hver med sin position, rotation, størrelse, farve og andre motor-egenskaber. Når du importerer filen, genopbygger Polytoria Creator denne struktur og behandler det hele som én enhed, du kan placere i en scene. Dette er forskelligt fra en .poly-fil, som gemmer en hel lokation eller et niveau snarere end en enkelt model.
Mange .ptmd-filer stammer fra Roblox-to-Polytoria (RTP) plugin'et. Eksport af en Roblox-model med RTP producerer en Lua-fil, som du omdøber til .ptmd, før du importerer den. Konverteren springer visse Roblox-objekttyper over, herunder MeshParts, Unions, SpecialMeshes og VehicleSeats.
Sikkerhed og tryghed
RISIKO: MEDIUMA .ptmd is a model definition rather than a standalone program, but Polytoria models can embed scripts, and files sourced from the Roblox-to-Polytoria workflow are plain Lua that was renamed. Because the format can carry scripted behavior, only import .ptmd files from creators you trust and review any attached scripts before running the model in your game.

dyb specifikation| Encoding | Text (plain-text model definition; the RTP conversion workflow produces a Lua source file that is renamed to .ptmd) |
| Container | Single self-contained model file holding an object tree |
| Compression | None documented |
| Typical size | A few KB to a few MB depending on part count |
| Structure | Describes a model as a hierarchy of objects (parts and groups) with their positions, rotations, sizes, colors and other engine properties, so Polytoria Creator can rebuild the model and drop it into a scene as one unit. |
| Integrity | None documented |
| Platforms | Windows, macOS, Web |
| Notes | PTMD is platform-specific to Polytoria. It is distinct from a .poly place file, which stores an entire level; a .ptmd holds a single reusable model. In the Roblox-to-Polytoria (RTP) pipeline, exporting a Roblox model yields a .lua file that must be renamed to .ptmd before Polytoria Creator will recognize it for import. |
