Missing previews, restricted 3D access, and loading problems.

No 3D button

• Use a computer or tablet. Phones have the 2D map, but not the 3D viewer.
• Sign in before opening 3D.
• The file needs a completed preview and 3D access enabled by its creator. A file can have a 2D map without a 3D preview.
• Try another map or prefab in the selector if the file contains several.

The preview stopped loading

Close it and reopen it from the file page. If access has expired, reopening requests fresh access. For a slow scene, try the Performance graphics preset.

Something looks different

The viewer uses preview assets and does not simulate every Rust feature. A missing model or visual difference in the preview does not by itself mean the downloaded file is broken.

Still need help?

Include the file link, the selected map or prefab name, your device and browser, and the exact error or a screenshot. This helps us locate the affected preview.
