Was getting bored and build a render routine to change the heightmap on the fly. And I created a nuke animation for it, maybe it will be used in later games for impacts of big spells and so, even texture change and persistent changes are used to create craters of explosions and such.
Due to the lack of explosions it looks a little strange, but I think its funny to watch.
The video is a big one, but I wanted it to show the ingame graphics as close as you can get.
