On Physx own page, they offer free commercial usage on Windows, OSX, Linux and Android, but explicitly not on iOS. I can’t confirm yet if that will continue to be true for independent licensing (PhysX in a non UE4 product), so I must confirm here:
Is the inclusion of PhysX in Unreal 4.x somehow licensed on iOS under the UE4’s license (ie 5% royalty), or will indie developers targeting iOS with UE4 have an issue with NVidia at some point?
