Tutorial: Effects Editor Well, this is actually a plug in, but it comes included with the toolset, so I've placed it here with the tutorials. N.B. Invalid values in the effects editor can cause the toolset to crash, and the editor may delete any campaign directory contents, so do a backup before you start! We're going to create just one effect to get started, but because I am far from being a dab hand with this editor, you can then use this experience to get comfortable with it: 3. FlowType is self explanatory - pick continuous. 5. Save your SEF file in the campaign directory AND somewhere else.
