Setting Up the Scene Render Layers

First of all, I built the ground geometry for the shadow and ambient occlusion layer. For the ruins scene it was quite challenging as I had to model not only the ground, but also the back wall and all bigger stones and pails on the ground. It wasn't necessary to model every single stone, because the shadow will be blurred and won't be completely black.

For the field scene it was much simpler. I could create only one nurbs plane and model it to align with the image. There was one difficulty though. It was hard to make sure the depth is accurate, so I went to the location and spend good couple of hour there trying to remember the topography of the area.

While solving render layers problems before, I created them and they were working. To save time and make sure they will work again, I didn't create new scene but imported everything to the working scene and just added stuff I need for each render layer.

So in the end I had eight render layers plus master beauty.
