I made an arrow curve in Design and continued editing it in Photo. I am trying to get a stroke that looks like fire, so I went to the stroke settings and set it to textured line style. In the brush panel, I selected the one that kinda looks like a fire(it doesn't). It will not apply to the curve's stroke. I tried using a different brush but none of them are being applied. What is the problem here? I will attach a screenshot and the file, but be warned. There is some NSFW things in the project I've hidden. Please don't tamper with them if not necessary.
