I bought only CC4 since I didn't need the extra features of Iclone 8, and I am totally content with iClone 7.
Although today I realized that I cannot push my CC4 content over to iClone.
The "send to iClone" option is disabled; so I saved my character as iAvatar; but when I load it in iClone7, I get an error and it does not load.
I tried with different content, including an actorcore character and the result is the same. Basically am I forced to export to FBX and re-import in iClone, like if I was using 2 totally disjointed apps? Are you implying that I need to buy both applications to retain the interoperability between the 2? Who came up with this and thought it was a good idea?

There are workarounds, sure, but the whole point for buying those 2 together is to have them interop with each other, without having to deal with conversion or other things like this. In my book I would expect content from either app to load even if the versions are different. I can still open files in Blender from 2019, that I made with blender from 2022, so what gives? Is this a bug?
