There are a few steps you can take to make a heightmap in Photoshop. The first step is to create a new document, and name it “heightmap”. Next, you’ll need to select the “Image” tab and click on the “Create Image” button. In the resulting window, you’ll need to provide a name for your image, and choose a size for your map. You can also choose whether you want your map to be filled with color or not. Once you’ve chosen your dimensions and image type, click on the “Create” button and wait for Photoshop to create your map.
