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, click the Local Engine item on the rail's bottom system strip, choose "Manage engine", and use "Reinstall Dependencies" on the affected pack.
  • For a deeper reset, open "Manage engine" the same way and use "Reinstall Engine".

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  • When packs are out of date, SimpliGen flags them.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.
