Terrain deformation in-game

[Klasus]

I have searched for how to do this on many forums without finding any good answers. How do I make a unit create a permanent deformation? It should be able to create rivers and such things when moving. I know how to create a terrain deformation actor, but I don't know how to attach it to the unit.

You cannot, you need to create many of them perodicly.

Sorry DSG you're usually right but not here.
If your 'deformation' has an actor you can attach it to the unit through triggers or move it around with triggers (create a unit with the attached actor and just make it unselectable, invulnerable etc)

I tried to attach it to a unit, when I move it around in-game, the terrain beneath it is deformed. The deformed terrain should stay deformed, but it doesn't when I move it around. It's only deformed at the position of the unit.

If I'm going to use Dr. Super Good's solution, I have to know if it will lag or not on average computers. I'm going to use 100-200 of these actors, placed in a line.

I am not sure what terrain deformation actors are. They might just be once off actors that make a change and then are usless, they might need to remain for the deformation to be effective.

In any case moving would require them to be a whole level more complex which is why I assume you cannot move them.

DSG Search up crater in game objects.
It's essentially just a unit that causes the ground to be deformed.

Anyways just physically attach the actor to the unit or have it moved to the unit's location every 0.01 seconds or something. Theres no need to create 100~200 of them.

 

[Dr Super Good]

The terrain deformation has to be done to the terrain mesh. It is not clear if the deformation actors support movement as that would require a whole level of complex mechanics to handle.

Well I've created them in order to simulate an asteroid hitting.
If they cant be moved then just delete the old one and create a new one.
