Toggle On/Off multiple checkboxes?
Hi all,
I’m trying to make a channel switcher control that runs the “Shift Channels” effect. I have a series of checkboxes for isolating red, green, blue or alpha channels.
Despite my attempts at using if/else if conditionals, I get a mess when I try to toggle off a checkbox by turning on another – is this just a limitation imposed by not being able to pass variables between effects? Any suggestions beside making .ffx presets for each channel?
thanks, pdebster

Are you trying to make a radio button control by linking check boxes together with expressions? I don’t think that will work because an expression applied to a check box would only have access to its own pe-expression value and its neighbors post-expression values. I can’t think of way to make that work.
Maybe you could use a slider instead.

Thanks Dan, I thought that to be the case, so I think I’ll just make presets out of the original ‘Shift Channels’ effect

Late post, so I don’t know if this helps…
Not understanding exactly what you are doing, but I’ve created complex check box features by writing code that references a null layer with check box/expression controls.
The different layers can have code with different behavior based on the same null layer control.
You can also have multiple expression controls on the null with conditional statements in the layer expressions (not the null) to make it work.
