# Build custom Effects

Custom firework effects can be built using the Depence asset builder, which gets installed alongside with Depence. 

## Create a new Firework Fixture

1. Go to New > New Firework Effect...
2. A fixture and DMX-Ignition object along with the default DMX mode has been created automatically.
3. Save your fixture into your MyLibrary folder: `Documents\Depence\MyLibrary\Firework\`
