Does Houdini support ue4 android or ios build to work?
u3d not support ,so how about ue4?

actually, that's not true, i am using it for unity/android as we speak! I'm not sure when they slipped it in there, but i'm super stoked.

We don't include pre-built iOS and Android binaries in the installer, but as far as I know it should be fine. You would need a C++ project in order to build the plugin for each platform.
