While working on conveting BFHeroes to BF1942, I experimented with making a projectile using a treeMesh. I didn't turn off DynamicShadows for it since I didn't expect it to work on treeMeshes anyway (since treeMeshes don't have a shadow mesh for obvious reasons), But to my surprise it had a shadow. But that wasn't the real surprise!

I made some objects on my simulator map use a treeMesh and turned on dynamic shadows. That was the result. Notice that it's a bit buggy when there is a lot of them on the map. It causes a CTD in fullscreen mode and bad flickering of all treeMeshes on the map. But this did not occur with the sticky TNT that I originally made a treeMesh out of. So I suspect it will be more stable if the map isn't littered with treeMeshes with shadows on.
One idea I got out of this was to use this to make terrain "decals". Like helipads and stuff.
