Effects
Here you can set the default resolution of live effect and locked effect resolutions.
New effects are locked by default: this will make any live effects you create locked by default, so they will not change if you move or resize them. More information.
Live effect resolution: if a live effect resolution is set to 'automatic', then any live effects on an object will, by default, be produced at screen resolution. If you wish to print your design you can set one live effect to a higher DPI and all effects on that object (as long as the other effects are set to automatic) will automatically be rendered at the highest DPI. It won't then be necessary to alter each effect one by one. Or you can set a different default in this window, and all live effects will be created at that resolution.
Locked effect resolution: this is the default resolution for locked effects. If you wish to change the DPI of a locked effect, you need to recreate that effect. Please note: this only applies to locked effects, and does not apply to if you have locked a live effect.
