RustSMF

RustSMF is a local editor for SMF, GLB/GLTF, FBX, DAE/Collada and OBJ models, rigs and animation.

Paint weights and export in one app. No external 3D editor required.

RustSMF owns its editor, formats, retargeting and contact solver. Building, testing and packaging need only this repository and its declared third-party dependencies. GaimEngine and other consumers are optional export integrations.

Download for Windows x64 · 0.2.1 preview notes · Sample model

Our test dummy playing Walk. Quickstart uses Signal Robot.

Try it

1. Install the Windows preview .exe, then launch RustSMF.
2. Download Signal Robot. Open rustsmf-demo.glb.
3. Choose Animate, open Tools, select Wave, then Play.
4. Use Save Project for editable .rsproj files. Use Export for models.

Try Sable, our original black cat, a self-contained GLB with Idle, Walk, Run and Sit. The Windows preview download still includes Signal Robot.

Windows requirements and download verification

This is an unsigned preview, tested on Windows 11 Home x64. WebView2 is required; the installer includes its bootstrapper, which may need internet access.

Download the .exe to install. GitHub's source ZIP and tar.gz are for developers.

Use SHA256SUMS.txt to check the downloaded file. For the default Downloads folder, PowerShell can calculate the installer hash:

Get-FileHash "$env:USERPROFILE\Downloads\RustSMF_0.2.1_x64-setup.exe" -Algorithm SHA256

Compare the Hash value with the installer entry in SHA256SUMS.txt. The release also includes offline preview notes and the MIT license.

Formats and practical limits

Current Windows source builds support rustsmf.exe --profile-dir "D:\MyRustSMFProfile" for a separate WebView and native autosave profile. Select an absolute new/empty directory, or reopen one already marked by RustSMF. A profile is locked to one running app. Without the flag, existing data locations stay unchanged. This option is newer than the public 0.2.1 preview; see the profile contract and installed proof.

Action	Formats
Open	SMF, GLB/GLTF, FBX, DAE/Collada, OBJ
Export	SMF, GLB, FBX, DAE

• GLB: includes textures in one file. Duplicate node names may change to keep animation bindings clear.
• SMF: cannot store scale animation.
• DAE export: one clip, linear transforms and one solid material per mesh. Use GLB for textures or multiple clips.

Missing required resources show an error. Lone FBX/DAE files can load without unavailable textures and show a warning.

See the user guide and current format limits.

Source builds open model ZIPs; choose a model if prompted. Extract ZIPs first when using the 0.2.1 preview.

Run from source

Clone or unpack the source, then open PowerShell 7 in the repository root. Install the declared Node range (^22.13.0 || >=24), Rust and the Tauri Windows prerequisites:

rustup target add wasm32-unknown-unknown
pwsh -NoProfile -File .\run.ps1 -Task setup
pwsh -NoProfile -File .\run.ps1 -Task run

run.ps1 -Task dev opens the browser app. Setup installs local WASM tooling.

Normal browser checks run project-owned Playwright directly. GenEye enrichment requires an explicit -GenEyeRoot; nearby repositories and ambient integration variables do not select it. The skeletal export developer CLI additionally needs a Git checkout for truthful source provenance. The installed editor needs neither Git nor the development toolchains.

After setup, build the NSIS installer with pwsh -NoProfile -File .\run.ps1 -Task package:windows. The command reports its path and SHA-256.

Standalone acceptance records the newer local source candidate separately from the downloadable 0.2.1-preview. That candidate does not replace the public preview or imply that private consumer motion is qualified.

Contribute and report problems

Contributing covers setup, local checks and a useful bug report. Frontend evidence maps supported workflows to executable checks. Maintainer state, work records and verification history live in developer docs.
