I want to import the asset to Unity 2018.2 as upgrading to 2018.4 breaks all of my prefabs. Is there a way to do so?
thank you very much for your support request.
Download Unity 2018.4, create an empty Unity project and import the latest UMotion version from the asset store. Then copy & paste the installed "UMotion Editor" and optionally the "UMotion Examples" folder from your 2018.4 project to 2018.2.
Please note, that Unity 2018.2 isn't officially supported anymore. I think it should still work though, but it's not guaranteed.
Let me know how this works for you.
