This is an easy to use ecosystem material designed for use in Vue 9 and Up ONLY, it will not work in any earlier versions of VUE.
To use simply load a flat plane (flat surfaces work better), for more realism you can simply create another rough terrain under your plane and apply another material to that, I suggest any of the Ruined Materials Packs to bring out more realism in your renders.
Scale your flat plane (the larger the better for this ecosystem).
Apply the SW NUKED 3.mat to the plane, preview and adjust the ecosystem scale and density to your likings. If you use this set in your project please give credit and feedback.
