Running a Unity 4.6 game on Unity 4.5.2 - Possible?

Hi everyone,

I have a question that if possible can be answered as soon as possible, possibly by a Unity worker.

  1. I have made a game using 4.6 as part of my Virtual Reality coursework; my other team members have used 4.5.2 for their part and the environment which we will be testing it is running 4.5.2.

Would my game be able to work on Unity 4.5.2 or not, as I would like to merge our scenes together in the build setting with some application level code as the final part.

Thanks for reading,


If you’ve made use of any features introduced in 4.6 (i.e. the new UI), this obviously won’t work in previous versions of Unity.

But everything else should be relatively simple: export your assets as a .unitypackage and import them into the other version. If that doesn’t work, you can simply copy scripts, models, textures etc. through the filesystem of the operating system.

You mean you are running 4.6 beta which internally still is anything from to 4.5.5f1.

Have look through the release notes for 4.6 and search for anything newly added that you are using.

But the best way for you is of course to downgrade to 4.5.2 which you can find here:
