Project Depot

Independent repository: https://github.com/OmsiModsBR/depot

Current Depot release: 0.3.0 (2026-10-30), based on openOMSI 0.2.16. Previous releases: 0.2.52 and 0.2.17 (rebranding only).

Historical source baseline from openOMSI: v0.2.16 (2026-10-07), commit c85b2e0dda13d219fd12d0496c653d20cdb54145.

Maintenance policy: stable base + selective upstream integration. See baseline provenance and integration policy. Build/test evidence and remaining limits are recorded in baseline validation.

[!WARNING] Early release. Expect bugs. Project Depot is in an early stage of development: things may be missing, broken or change between versions. Please report problems in Issues.

Project Depot began as an independent project derived from openOMSI, a Rust recreation of the bus simulator OMSI 2. It retains that technical foundation: 64-bit, multithreaded, with a modern renderer (Vulkan / DirectX 12 through wgpu) and an optional DirectX 9 renderer on Windows.

The project's explicit goal is to achieve 1:1 compatibility with OMSI 2, including its existing maps, buses, scenery, scripts and mods. This is a development target, not a claim that complete compatibility has already been achieved. Alongside that goal, evolutions to the simulator's physics and simulation are a development priority, while preserving compatibility and a stable base through selective upstream integration.

What's new in 0.3.0

Depot 0.3.0 (2026-10-30) is the first release numbered by hand. The full list, with the pull request behind every item, is in the changelog; the release notes summarise it. Highlights:

• DirectX 9 renderer (D3D9Ex), off by default. Settings → Graphics API offers "DirectX9 (D3D9Ex)" on Windows ("Automatic" never picks it). It draws the scene and its materials, lamps and light maps, the sky, mirrors, light coronas, smoke and particles, the interface and the maps, with an optional snowfall. Graphics stays at Vanilla under it. It is new: its look is still to be compared with the original in the game.
• New in-game interface. A new Esc menu and the pages behind it, the Alt bar (a tap of Alt, never pauses the game) with Add vehicle and the rest of its buttons, a new loading screen, an end-of-trip report, and windows in the Windows 11 look.
• Information bar (Shift+Y) redesigned, with Full, Two-tier, Split and Custom layouts, a position and a frame-rate part.
• Navigator and city map. Compass, terrain view with contour lines, street names under the pointer, lines panel with timetables, a top-view minimap option and new vehicle pictograms.
• Launcher redesign. Windows 11 look with Maps as the start page, Vehicles grouped by manufacturer, Profile and Sessions in one page, a Timetable planning page, Setup and Settings rebuilt, accent colours, a sidebar or a top bar, tooltips on every button, and a launcher that opens at once.
• Diagnostics. Integrity check of maps and vehicles (also against a baseline folder), the AI traffic tab with editing of a map's AI lists and parking lists, and a detailed log switch.
• Vehicle physics and passengers. The vehicle physics refactor is complete; the weight of the passengers aboard is added; steering linearity is on by default; articulated buses no longer fold into an L at speed; AI vehicles steer by their own .bus files; passengers use every door of an articulated bus, keep the height of a high platform and complain again when the saloon is too dark.
• Performance and safety. No more drop to a few frames a second while paused in traffic; a content file or map package can no longer point the game at another drive or computer; mods install from a .zip only.
• Removed. LAN play, the dedicated server, voice chat and plugins, switched off since the first Depot release, are gone from the repository.
• Hidden for now: an original OMSI 2 mode in the launcher (off by default, Windows only).

Earlier releases: 0.2.17 was only the rebranding (no gameplay, renderer, physics, simulation, scripting or multiplayer changes; release notes), and 0.2.52 was the first with behaviour changes: articulated buses and trailers as separate bodies, refactored vehicle physics, an independent outside-view field of view, navigator map packages, a pusher joint, timetable and sound fixes (release notes). Several of these are validated only by automated tests, and the physics changes are not shown to match OMSI 2 yet: 1:1 compatibility remains a development goal, not an achieved result.

[!IMPORTANT] Project Depot needs an original copy of OMSI 2. It contains no game content of its own: it plays on the maps, vehicles and other files of an installed OMSI 2 and will not start without one.

Feature highlights

How to read the labels below. 1:1 goal: the feature is meant to behave like OMSI 2; it is checked by automated tests and traces, and is not claimed identical until it has been compared in the game. Deliberate improvement: it differs from the original on purpose and is recorded as such. Depot addition: OMSI 2 has nothing equivalent. Experimental: new, off by default or not yet compared with the original in the game. Every item below is in the 0.3.0 release; the pull request behind each line is in the changelog.
