Now, add a Displace modifier to Ground01. Attention not to add a Displace Mesh (WSM) modifier, that's a completely different thing and it's not what we're going for this time. Set the Strength to 180 and then click on Map in the Image tab. The Material/Map Browser will appear and we will Browse from Mtl Editor. We only have the Smoke map we set up previously, so we choose that one
Now the ground should be displaced by our Smoke map. It looks pretty low poly, so we're going to set Ground01 to have 200 Length and Width segments, instead of 50. But make sure to save your scene before doing this. You could experience performance problems if you increase the segments, so if you simply cannot maneuver well, leave it at 50 segments and you will only set it to 200 when you render.
