Preset Flow merges a previously saved Particle Flow setup into the current scene. It allows you to use the flow as an event within your current flow, or as a starting point for a new particle system.

Before you can merge a scene with Preset Flow, you must save it with the Preset Manager. A preset can include Particle Flow elements as well as standard 3ds Max objects.

To add a Preset Flow, drag Preset Flow into the event map of Particle View. The Select Preset Flow dialog opens. Highlight a preset and then click OK, or simply double-click a preset name.

When you drag a Preset Flow in Particle View, the global event appears where you drop the flow, and additional events appear in the same spatial relationship as when they were saved in the preset (if you add the Preset Flow from the Edit menu, it appears where it was saved from). All items that were added by Preset Flow are selected in the scene and in Particle View.

To revert the merge, activate the 3ds Max window (by clicking outside a viewport, right-clicking a viewport, or closing Particle View) and then press the Delete key.

If the Preset Flow contains geometry, operators, or other items with names identical to those in your current scene, the standard 3ds Max Duplicate Name dialog appears and prompts you to change the names or skip the items. If you skip the PF source item, the preset will not merge.
