The Message Log is an area in the Filter Editor that lets you see error messages produced by components:
An error in a script, or a loop, or with an Intlsider range automatically opens the Message Log. It can also be opened or closed via the View > Show Message Log menu command, or by pressing Ctrl⌘+L. Additionally, it can be closed by pressing the Esc key.
Non-error messages are shown in gray, error messages are dark red. The most recent message is shown in bold.
If an error originates in a Script component double-clicking the error message in the Message Log takes you to the location where the error occurred: Filter Forge selects the script component that generated the error, opens its Script tab, and, if the message has a line number, positions the cursor at the appropriate line. Errors in Loop and IntSlider components are marked with a Connection Warning and cannot be located via double-clicking.
The contents of the Message Log are not saved between the Filter Editor sessions – the log resets every time you open the Filter Editor.
