Waterfall bundles an ingame editor to edit effects and generate configs

Basics

Before editing a new effect, you have to set up a minimalist version of it in a config. See the guide here.

Once this is setup, go ingame, launch a ship with the engine involved, and click on the Waterfall icon on the toolbar. Note that it is highly recommended to do all editing on a vessel with only one copy of the engine you wish to edit

Basic UI elements include several panes, described here

Controllers

These are the controllers associated with the effects in question.

Effect Module List Pane

[IMAGE HERE]

This is the list of effect modules on the vessel that is currently active. For example, a multi-engine vessel with two ModuleWaterfallEffect entries will show two separate buttons, clicking each of them will load that module's Effects into the Effect List Pane

This shows the list of effects associated with the effect module currently selected. This pane allows the bulk of the editing of the Effects.

Export Pane

Exporting Effects is a bit meh right now, but that's ok. Each button will do a type of export

• Export All to Log: This will generate a set of EFFECT nodes for ALL the ModuleWaterfallEffect modules on the part and dump it to the KSP log.
• Export Selected to Log: This will generate a set of EFFECT nodes for the selected ModuleWaterfallEffect module and dump it to the KSP log.
• Export Selected to Clipboard: This will generate a set of EFFECT nodes for the selected ModuleWaterfallEffect module and put it on the system clipboard.
