Game Development programs can produce “Hight Maps” as “.RAW” files which are just grey scale images which determine the hight based on the value of the pixel color. When opening the file in “PhotoShop” this is the dialog box.
Right now “PhotoShop” is the only photo editor that can open these files and there isn't any reason Affinity Photo shouldn't be able to do the same. There are many people like me who are trying to remove themselves from the Adobe eco system and if Affinity would add this simple feature it would help us Game Developers / 3D artist say goodbye to Adobe. I’m attaching a sample of the “.RAW” file for you to test.
When opened in Photo Shop the "terrain.raw" image looks like this.
