Entity Tool - Ability to place objects ranging from helicopters to barrels, and buildings. There are translate, rotate, and a 'face cursor in world-space function so far.
Terraform Tool - Adjust terrain up/down with adjustable brush size.
Here is a link to the video I uploaded showing the two tools -
This also opens up the ability to have destructable terrain, the Havok physics representation is updated in real-time. The texture locks on the GPU version of the heightmap are the bottleneck at the moment. I'm really excited about this :-o
I'll be improving the editor and adding a lot of stuff like trigger boxes for gameplay events, more customization of the environment/time of day, and all the standard stuff like road and fence tools. Hopefully I can get 2 more videos of the editor uploaded showing different tools and the overall progress without getting into game-specific content ;-)
Here are some screengrabs from the video for those who don't wanna watch it :-p
