We want to allow the import of user-created maps. However, it’s not yet defined when this feature is available and how it exactly works.
Import of height maps is already implemented (for internal testing).
Given a height map, splat maps are currently generated automatically in a shader on the graphics card. This happens every time the camera changes, and only for the visible region, with higher resolution close to the camera and lower resolution far from the camera. This way, we don’t have to store the splat map, it’s a function of the height map.
It might be straightforward to implement the import of splat maps (and simply disable the shader generation of splat maps but read the imported splat map).
Thanks for the suggestion!
