Scaffolding, Ivy, and Lighting Improvements.

The forest ruins project is moving right along. Considerable improvements have been made to the lighting. A lightmass importance volume was added to allow light bouncing. There may be a few more tweaks for the final product, but I'm happy with it. 

I've added some scaffolding models along with some details like hanging rope and rivets. 

The ivy has been optimized. Polygon numbers have been cut considerably, and overdraw of the transparent pixels has been kept to a minimum in order to keep performance up. The ivy took a lot of work, but the results speak for themselves.

What's next?

The forest ruins project is wrapping up! I'm in the process of creating tiles for the floor, a section of crumbling roof, patches of grass, and some stairs to a platform at the back. All of this will be shown soon! 

For now, here are some shots of the ivy and the scaffolding. Click to enlarge.
