You could probably use simple models for some instances, like if a tank explodes or something it creates a crater model which spawns around it, as long as it's something that doesn't happen very often you should be OK, you could also cap the number of craters or perhaps only spawn one every so often. It'd give you a bit of environment alteration that should look acceptable without requiring any major code changes or anything. Combine it with a decal to help blend it into the terrain underneath it and you should be fine.
well you are so superior i forgot about thinking and solely rely on your wise insights - its a bit of a pain when going to the toilet in the morning tho
