    If UDK increace Nvidia PhysX function , some Royalty ??

    If UDK increace some Nvidia PhysX function , may fluid water fusion , smoke volume ... need to give some Royalty to nvidia ??

    You'll need to email physxlicensing@nvidia.com before you sell your game if you use PhysX *at all* (Unless Epic did that en-mass for all UDK licenses). You can ask them there.

    Though you'll almost definitely NOT be able to integrate PhysX into the UDK -- not from a licensing standpoint... but from a technical standpoint. Even if you can add in the libraries into the UDK directory, I doubt the editor or engine would know what to do with it. Especially since the engine implements most of the features by default anyway.

      Isn't PhysX pretty much already implemented, just not the less useful more extremely cpu intensive functions like you are asking about not available? something like that?

        Yes, UDK uses PhysX, and the license carries across for free. You're stuck with what functionality Epic have exposed though.

          oh ! thank very much , I see why UDK can't dynamic fluid function , really Royalty problem...

            If I had to guess, I would say that Speed Tree gets some of that 25% royalty as well. It's really not a bad deal, when you look at what all is being offered.

              i'd say the problem more likely, is that no one is going to use those functions, because they aren't useful for much of anything outside of a demonstration. we've been telling you this for months. the functions you keep complaining about not having available are things that take huge quantitites of cpu power to operate.

                This is not complain ^_^ , don't misunderstanding my mean , you keep to say fluid fusion is huge quantitites of cpu resource , but the youtube video , the cryostasis , avg 40 - 60 FPS for GF280 , and the level have cloth / Kactor ... together , not only dynamic fluid , so ... why you keep to say fluid fusion(dynamic fluid ) consumption huge cpu resource and not useful??
