If you're technique works well and accomplishes the goals set forth in this thread, then I'd be willing to purchase your 2.5D kit (and provided I'm satisfied with the end result of course). You mentioned you might sell it cheap either in this thread or the other one. If it works on blocks, then that would be ideal. Given there's no updating of the level and it's simply taking a snapshot, the slow nature of shaders on non-model blocks shouldn't matter
