For your game packs you could make floors also like in Oblivion or Follout 3 , good ones with normal maps ! Even Ogre 3D will support normal maps on terrain system , it's already working !
Yes. Great idea. I have to check that. But if you can achieve great quality, you can do it also and we buy it from you.
