I don’t believe the landscape terrain system supports dynamic modification right now.

What you could do is spawn a decal at the impact point. Even a normal map could give the impression of some surface depth. Coupled with a scorch mark decal, smoke,etc.

What about on a smaller scale such as footprints, bullet hits and scorching from fire?
Other things like snow with footprints
water from rain with splashes etc?

Decals are used as well. splashes are down with particles. check out the splash in the reflection demo.
check out the crater in the elemental demo.

What about a particle bluerpint-system?

Yeah I’ve been looking for a solution to this myself. Even had the crazy idea of real-time applicable boolean operations to simulate the crash and slide of something like a big meteor crash-landing. A system like they had in From Dust would be perfect, but alas, I lack the brilliance to write a plugin/modify the engine for it to do that lol.

Have you tried using decals with tessellation?

Except that I was talking about decals.

Here is a simple tutorial for decals.

Another way is vertex manipulation.
