Good morning from the DEV team, guys!
First, let me assure you that nothing at all changed in the development of the C4D plugin since the merge with Chaos Group. We have our roadmap of features that we want to implement and we're working on them as best as we can and nothing about the merger influences that.
Now about the release, we hope we will make it today - yes, some of the features will be missing, for example the material stack support won't make it at all. As for the rest of the features, they will be in the release in a more or less complete way. We are especially looking forward to giving you access to the interactive rendering.
That being said, occasional crashes in the interactive renderer are to be expected, so I wouldn't recommend to use it in production environment (actually, I wouldn't recommend any beta release of any software for production in this regard :-) ). If we didn't have the release date set yet, we would probably spend two more weeks polishing the interactive rendering, but this way we will be able to collect more feedback from you - the real users, while at the same time giving you the possibility to test the IR for yourself for the first time.
Thanks for your continuing support!
