The subject states the goal. I want to create footprints in the sand when someone walks by. I don’t want to use a flat texture laid on top of the terrain. I’d like some depth. So, here is my thought on it.
I create a plane, get the terrain texture where I want the footprint to be and make that the plane’s texture (if I had pro, I would probably go with a render texture here), apply a bump map for the footprint, maybe fiddle with transparency a tad to blend it better (potential issue if ligthmapping is used, as actual terrain texture will not have any lighting applied and the terrain probably will), and then place the plane on the surface of the terrain.
Will this work? I know there is a crater script out there for actual terrain deformation, but a foot print is too small in relation to terrain resolution for that to work (and there is a resource overhead where the crater script holds all of the terrain HM verticies in memory). I have no access to my machine for the next couple of days, so I’m stuck designing without testing.
