For some reason, only a single effect on one of my layers is not showing up when I attempt to export (Pattern Overlay). You can see that the tree-like pattern on the palm tree itself is missing. I have attached screenshots of before the export, during the export, and a solid view of the layer panel. I also just updated to the latest version of Photoshop today. Please let me know if I'm missing something! I'm a very new beginner to Photoshop as well.
Would it be possible for you to share your workflow, ie I do this, then this, and then this.... so that we can follow along with what you expect to happen vs what is happening? We are happy to try to help you figure this out.
