My ADHD must be kicking in, because I solved the problem, right after I posted this question.
I used the Asset Importer and set it to filetype: texture. Located a .jpg of the texture I wanted(in my case it was pebbles on the ground), gave it a description and saved it to the correct asset repository.
I then went into my asset definitions folder, located myfile_texture.asset
is the name I gave the texture when I downloaded it, and opened the file in a .txt editor(make sure the file stays a .asset
file and you don't rename the extension), and added this bit of code(that I copied by looking at another texture file that I tested and knew already worked in World Editor).
<Property name="TerrainTexture" value="true" />
Note: This needs to be added after </Files>
, but before </AssetDefinition>
After I copied that bit of code into my texture-asset file, I was able to apply it, inside the properties window, when I clicked on terrain display(where you can set each of the different textures). When you go to change the texture on part of the terrain, a new window pops up with a list of textures to choose from. The new texture was listed and correctly applied, when I selected it.
