To create natural environments in Overgrowth, we will need to be able to quickly populate the landscape with lots of semi-randomized rocks and vegetation. Doing this is pretty tedious with the current editor toolset. So, I’ve begun work on a ‘paintbrush’ tool for quick object placement. It’s still in its early stages, but I’ve found it fun, so I thought I’d share a video of it in action!

For those of you with access to the alphas, this coming week you will be able to use the paintbrush as follows: First, load an object. Then switch to the “add object tool” (just press ‘3′). And finally, click and drag your mouse around the landscape while holding down ‘b’. As shown in the video, you will also be able to use the sliders in the “Misc” palette to change various properties of the brush, such as scale, jitter, and whether or not objects should be placed on top of each other versus just on the terrain.
Do you guys have any paintbrush-related suggestions? This implementation is still very rough and I’d be glad to incorporate your ideas in later versions!
