See my post to your other post. I am thinking if I can use the 17 channels somehow that Unreal now defines in 4.26 this will allow me much more flexibility for my needs of encoding in a DAW or NLE. But I am thinking from I read in this article about Max Hayes is that they might be working from a Ambisonic source to derive channel information now and that there is now an Ambisonic library. When I asked on Twitter where this was located, I received no response. My thinking is this is where Unreal 5 is going allowing much more flexibility in how audio is recreated at the endpoint.
