I think that it would be much wiser for Acknex007 to create a game that would sell like hotcakes. Then there would be no question of legality involved, instead everybody would pay for playing his game. It's very-very tough to create a 3dEngine, as its already very hard to create one and it would be even hard to support further development. And in this case where you dont have the source of the engine itself, there is no chance that there would be money in it.

There have been means, of this kind of functionality to hack other peoples work but its a very short life for such products. I would like that you stop this kind of activity pronto.

Better take my advice and invest your energy into creating a very good game so that you and everybody else is proud of.
