Export PNG is now available for 4.26 and 4.27! You will need it to export heightmaps from this kit! You can use Export PNG for UE4.27, and import it into the landscape/heightmap importing area of the editor as of now, you just CAN NOT yet export your PNGs FROM UE5, that has to be done in one of the other lower versions, like 4.27, 4.26... whatever the HeightMaps Pack is built for. Yes, you can export from 4.27, edit up the heightmap and reimport it into UE5's landscape editor, and it will work. I personally tested that and all packs are now in the process of moving to UE5 releases as well.
HeightMaps Pack Z1 - The Lost Valley Collection is the newest in a coming line of heightmap themes. Over the last year, I have been quietly designing new heightmaps. This pack features 100 valleys to explore, in the 4k size (4033 x 4033). The pack is great for games like FPS, Sci-Fi, RTS and many others. A lot of users like using my packs for off road like games and some even used my heightmaps in VR related landscapes.
This is the first in 3 new heightmap packs that are coming under the "Z" lineup. Each will feature very unique themes, and each is created by hand by myself. I really hope you enjoy the new pack!
