As I worked on Crawford Grain, I knew that I was going to have to model the gravel parking lots but I wasn't sure how I was going to do it. I finally figured that the best way to do it would be to use the real thing.
So, I went out along the gravel road that I live on and scooped up some dirt that had washed off the road. I took it home and baked it in the oven for an hour or so to dry it then sifted it. What I ended up with were some very fine particles of crushed gravel about the size of mason sand. It looks perfect.
I then spread a thin layer over the parking lot, wet it and glued it down. When I wet it, it darkened up a bit but I figured it would lighten back up after drying. It didn't. However, it does look EXACTLY like a parking lot with a fresh coat of wet washed gravel that we see in my area. I need to tone it down a bit and make it look like dry, used gravel. I guess that's where weathering comes in!!
I'm now trying to figure out the best technique to tone it down. I'm thinking maybe one or a combination of three ways: 1: Go find some lighter toned dirt, sift it to a power and brush it on, 2: Use some weathering power that's a lighter tone and brush it on, or 3: Some paint either airbrushed on or washed on.
Suggestions?
