That would make more sense to me and might be worthwhile to look into in the future. For now though, I thik I'm satisfied with the QTVR that I already have, although, I'm not exactly sure what Peter's intended purpose for VR is to begin with (I could have just missed that). I do like the platform that Unreal provides but like Peter, I work off of something that has less than the recommended tech. specs. for programming. I work off of an iBook G3 800MHz 640M Ram and until I can upgrade to a better system I don't think Unreal is a viable option. Don't get me wrong however, I am definitely interested in it as I am always in awe by the games which utilize it. Doug
