Updating the app and engine
Keep SimpliGen, the local engine, and your presets current.
There are three things that update independently in SimpliGen: the app, the local engine, and your preset packs.
The app
New SimpliGen versions bring features and fixes. Install the latest version when prompted or when a new release is announced. Some preset improvements require a minimum app version, and SimpliGen will tell you when an update needs a newer app.
The local engine
The local engine (the portable Python and ComfyUI that powers on-device generation) is managed for you.
- If a generation fails due to a broken or missing dependency, use Repair Dependencies on the affected pack.
- For a deeper reset, use Repair / Reinstall engine in Settings → Local Generation.
You only need the engine for local generation. Cloud generation does not use it.
Preset packs
Preset packs update separately from the app, through the Preset Store.
- When packs are out of date, SimpliGen flags them.
- Use Update all to bring every pack current in one click.
- Updating packs is what makes new and fixed presets appear, and what enables new cloud options.
A good habit
If something looks off with a specific preset, update its pack first. If something looks off with the whole app, update the app. If local generation breaks, repair the engine or its dependencies.
