Learn when MSFS 2024 scenery can be converted to MSFS 2020, which source files are required, and why copying or editing a package usually fails.
Microsoft Flight Simulator 2024 scenery is not automatically backward-compatible with Microsoft Flight Simulator 2020. A developer can sometimes port a simple scenery project by rebuilding its original source assets with the MSFS 2020 SDK and replacing unsupported 2024 features. A compiled 2024 package usually cannot be reliably converted.
Is MSFS 2024 scenery backward-compatible with MSFS 2020?
No: MSFS 2020 cannot be expected to read scenery built against the newer MSFS 2024 SDK. The two simulators have different toolchains, supported schemas, library objects and platform features. Our summary of the platform and add-on differences between MSFS 2020 and 2024 explains the broader reasons.
A simple package containing only older, unchanged scenery elements might happen to load in MSFS 2020. That is incidental compatibility, not a dependable conversion method. Ground materials, object placement, terraforming, exclusions, lighting or airport data may still be incomplete even when the scenery initially appears.
Compatibility is also not reversible. A newer simulator may retain support for some older packages, as covered in our guide to using MSFS 2020 add-ons in MSFS 2024, but MSFS 2020 cannot understand features introduced after it.
Can an end user convert a downloaded scenery package?
An end user with only the installed package can rarely produce a proper MSFS 2020 version. Compiled scenery files are build output, not an editable project, and Marketplace-delivered content may also be encrypted or otherwise protected.
Changing a manifest, lowering a stated simulator version or copying the package into the MSFS 2020 Community folder does not translate its scenery data. A mistake we see constantly is treating the manifest as a compatibility switch; it describes the package but does not rewrite unsupported models, materials, XML elements or dependencies.
You also need the creator's permission to modify and redistribute the scenery. Buying or downloading a package does not grant access to its source or the right to publish a converted edition. Hand-installed conversion work is a PC process; Xbox users cannot place an unofficial package into a Community folder.
Which scenery assets can be reused?
Original source assets are often reusable, but every asset must be processed through the MSFS 2020 toolchain and checked against its supported features.
| Scenery component | Potential use in MSFS 2020 | Work required |
|---|---|---|
| Original model meshes and textures | Often reusable | Export with MSFS 2020-compatible settings and recreate unsupported materials. |
| Airport or placement source data | Sometimes reusable | Remove newer schema elements, reopen it in the 2020 editor and verify every placement. |
| Source aerial imagery | Usually reusable if rights permit | Rebuild the associated polygons, tiles and package output for MSFS 2020. |
| MSFS 2024 library objects | Not available as 2020 dependencies | Replace them with 2020 objects or licensed custom models. |
| Compiled scenery files | Not suitable as project source | Return to the editable project and rebuild rather than attempting to rename or patch them. |
| Encrypted content | Cannot be converted by the user | Obtain an official MSFS 2020 edition from its developer. |
How do developers port MSFS 2024 scenery to MSFS 2020?
A proper port is a source-level rebuild using the MSFS 2020 SDK, followed by testing inside MSFS 2020. It may be a short job for basic object placement or substantial redevelopment for scenery built around 2024-only systems.
- Confirm the rights and source files. Work only from an editable project and assets that may legally be modified. Keep the original 2024 project untouched.
- Set up the MSFS 2020 SDK separately. Do not use the 2024 compiler to produce the final 2020 package. Our introduction to using the MSFS SDK and its separate toolchains covers the essential project workflow.
- Audit every scenery element. Identify 2024-only object types, materials, default-library dependencies and project properties. Replace or remove anything the 2020 editor and compiler do not support.
- Import the reusable source assets. Re-export models with compatible settings, rebuild materials and recreate placements that cannot be read safely from the newer project.
- Rebuild with the 2020 SDK. Resolve compiler errors rather than suppressing them or editing the finished package metadata.
- Test from a clean Community folder. Check for missing dependencies and conflicts before adding unrelated packages back.
- Inspect the scenery in detail. Verify terrain shaping, exclusions, runway and parking positions, approach alignment, day and night materials, windsocks, lighting and collision behaviour. An airport that merely appears on screen is not necessarily a successful port.
Why does copied MSFS 2024 scenery fail in MSFS 2020?
Copied scenery fails when MSFS 2020 encounters unsupported compiled data or references assets that exist only in MSFS 2024. Depending on the package, it may be ignored entirely, display missing objects or textures, alter terrain incorrectly, duplicate an airport, or cause loading errors.
If a copied package seems to work, test it away from the main terminal as well. Taxiway signs, apron materials, exclusion rectangles, custom aerial imagery and night lighting commonly reveal problems that are not obvious from the runway.
When is conversion not worth attempting?
Use a native MSFS 2020 release whenever one exists because it has been built and supported for that simulator. Porting is reasonable only when the editable source and permission are available and the scenery relies mostly on features supported by both versions.
- Choose the native 2020 edition for a finished, supported installation.
- Rebuild from source when you own the project and can replace its unsupported features.
- Stop at a compiled or encrypted package because there is no reliable user-level conversion path.
- Recreate the scenery when 2024-specific features are so central that replacing them amounts to a new development project.
