Is there a way to get water on the ground with the world editor as if it just rained, and is it possible to enable pbr materials with the world editor?
Enabling PBR is not easy, it's not just clicking some buttons, it requires redoing a lot of the textures which can take weeks of work. But wet ground is possible, it's on driver training map.
