KatSplatter Tutorial

1. Base textures

   Get your base textures.
   • They are not necessarily tileable,
   • They have to be of the same size, for example 512x512,
   • They have to be bmp files.
   

2. Load your base textures

   Load your four textures by clicking on the "Add Texture" button in the left panel.

3. Create terrain

   Generate a heightmap by adjusting variables, and clicking on the "Gen HillTerrain Heightmap" button on the right panel.
   You can also load one of your heightmaps if you don't want to generate one.
   The generated heightmap will have the same size as your textures (512x512).
   Change some parameters on the right panel and generate it again. The seed value allows to generate the exact same heightmap between sessions.
   See details about Hillterrain algorithm here, or check the file "Config.txt" as it contains infos about these values.

4. Blending textures

   Click on the "Splat Textures" button on the upper part of the window.
   That's all!
   Adjust the "Altitude" value of each texture, and check the result by pressing the "Splat Textures" button again.

5. Export files

   Files are already on disk: the heightmap is called "Hillterrain.bmp" and the final texture is called "final.bmp".
   However, you might want to click on the "Export" button to save your files in png format, and test them in your 3D engine.
