Can anyone help me with using the Flood filter from Flaming Pear? I am using Windows 10. When I call it up from Affinity Photo (which I am very new to) the PlugIn opens fine but nothing in the filter is operable (except rolling the die ). I tried to use the Marquee tool on my background layer before sending to this plugin but then the image that opens in the filter is a semi transparent image (and none of the tools in the filter worked). Without the Marquee tool the filter opened but no image. Help!
