Hey so i have created and painted a terrain only to find out that i left the resolution of the textures to 512. Now is there i way i can change this without it removing all of the textures. Im a programmer so i dont really know much about this stuff so this might be a very dumb question.
There is not a function build in to scale the hightmap and the splat-map to the new size.
If you change the size , your hightmap and splat-map will be gone.
