I would like a function that would enable you to place an object1 over another object2 ie terrain object. Have both objects overlapping and delete from the terrain object (object 2) the mesh data. Glue object1 to object2 and then when you update the terrain you will have a crater created at the intersection of the two objects. This would allow for bullet dents to be placed in walls and craters in terrain objects left over from explosions etc

What you're suggesting is a boolean operation on arbitrarily shaped meshes which is both computationally expensive and incredibly complex to solve correctly for all cases. It's not something you want to be doing in real-time.

This is overkill for the effects you actually want anyway. Terrain craters can be achieved by moving the heights of the terrain points down around the area of the explosion. Bullet dents in walls are better done with decals. You can get a decent depth effect using bump/normal mapping. It's not perfect, but it won't cripple your machine

It might be worth looking to see of the CSG functions made their way into GSDK

Come to the last Unofficial DBPro Convention (http://convention.logicstudios.net/)

I think what i really want is to dent an object

basically a function something like

void dbDentObject(id,objposition,objradius){
........
........
........
}
