Now Click OK. If we export the virtual effect now it will no longer have the Shadow Tone Slider.
We can move the slider up in the pile back where it was and also rename it to Shadow Tone.
Pick the Unsharp Mask and drag it to the canvas over the connection where you want it inserted. If you drop it over a line it will be inserted there automatically, if not you will need to reconnect it to the other boxes.
Once you export your new Virtual Effect, you can close Reactor. The original application will have displayed this waiting dialog with the Finish and Reload Effects button. Pressing the button will tell the application (Player or DAP5) that the editing is over and it should look in all the folders for any changes and rebuild the list of effects.
Depending on which way you exported - overwriting or making a new name, the new effect will now have the additional Sharpness slider.
And that’s the basics of editing your filters.
