I improved the Heightmap editor with:
- Load heightmaps from the existing and the one you would create to edit them.
- I also added the possibility to draw with a square brush.
- To generate the texture, I added the ability to enter a name as you see fit rather than generating a name in increments as I had done before.
- And finally, I added a reset button to reset and thus recreate a new heigtmap if needed.
I already have ideas for future improvement to create a texture mixer in the 3d preview taking into account the different elevations. Maybe also add an undo/redo. And be able to generate a heigtmap from the 3d terrain after sculpting it with the sculpting tools. But that will be for a future version.
You can try it here. I made an online version to download the result :
See you soon.
