In Affinity Photo I created a star shape from the shape tool menu. I rasterized the layer and wanted to distort the shape, so I went to the filters menu and selected Distort and selected the Pinch/Punch filter and I got a little slider box which did nothing when the sliders were moved. I tried other filters from the same menu and nothing happened to my shape when I moved the sliders. This should be a simple function. I've looked online for the answer but couldn't readily find it, and I don't have time to spend hours searching through videos or topic threads. Could someone kindly tell me what I'm doing wrong? Thank you.
