Is there some way to change the ground texture appearance? I was trying to make a sand, gravel or asphalt driveway to house I build, but even digging out the existing terrain and replacing with suitable blocks, it doesn't change the color...it is still showing as grass texture even if when you dig it, it is the correct material...I really don't even care if it is the correct material, I just was wanting it to show as a different material. Paint brush doesn't work....
