I’m starting work on a large open terrain map, and am dreading doing the textures thanks to Hammer’s shitty way of handling it for displacements and blends. I’ve heard the idea floating around that sometimes people use large resolution textures made in photoshop, and just apply a single texture to the terrain ala regular brushwork, but I after searching around a bit I haven’t found any resources on optimizing it or what texture resolutions work best. Maybe I didn’t look hard enough, who knows.
Has anyone here done it? Are there any performance issues involved with using such a large texture? Would it be better off to break it down into a few smaller textures? I’m thinking this would be a much better alternative to using displacements as I wouldn’t have to worry about cutting them up in all sorts of different ways to get the detail I want.
