I've felt much the same way since... well, basically since I bought CC3 myself and tried importing into Unity!!

FWIW, if the powers that be are serious about finding developers to update the Unity setup scripts, they should post something on this thread! I actually have a small team of developers so might be able to spare one or two to do the work -- especially given that we're roadblocked getting any new character imports working anyway!

How so?

If you use 2019.3 or 2019.4 built-in or hdrp it works fine. Just as a gateway.
Once you're done just copy the character folder to your desired Unity project and it's all good. Consider it a sandbox project. You most likely need one anyway to test things before sending to your productive project.

I've imported a lot of characters (clothed, with smart hair, beard and brows as well) recently into Unity 2020 and 2021 and had no road blocking issues.

Any update on this? It's 30th of June.

I feel like we're all foaming at the mouth at this point.  lol  I can only imagine what I'd feel like if I had made the purchase.

My wife has just said, "Buy what you need to, just get the game finished."  My cart has had 3 items in it for a couple days as I ponder my situation.

I'm waiting for July 6th sale at Unity for their 3D assets to go up on their big sale.  CC3 is on their "Mid-Year Special" that ends today, but they haven't posted on this thread since opening it, except to point back to the original message.  I don't want to miss a sale on a software package that may be very important to my pipeline, but I wont waste hundreds of dollars on something that doesn't get the customer service that is expected, ESPECIALLY when the update THIS MORNING is:

Yes, it can of course be imported, but requiring us to take these steps (using several Unity versions, rotating bones to arbitrary numbers etc) aren't really acceptable when we've paid a lot of money for a product that claims to support Unity.

But I think what upsets people the most is the silent treatment we've been given for a year now.

They're saying that they'll continue updating auto-setup and share open source code in early July, in this thread. See the link below for that announcement, some upcoming iClone8 features, and a CC4 tease:

https://forum.reallusion.com/486954/What-to-Expect-in-the-Second-Half-of-2021

I like that something is mentioned, but they didn't really say.... anything, really.  They just repeated the original message from this thread.  "We might do something, or we'll make it open source and hopefully somebody else will do something."

What I would like to read is, "We've heard you, we're working on hair, eyes, shoulders."

Yeah silent treatment is annoying but again I don't find the Unity version to be an issue. The shoulder topic is something you'll always have to deal with if you have characters of different proportion etc. I highly doubt this would be on CC side of things, but I might be wrong. Rotating bones has always been a topic for Animation retargeting, for any game engine or 3D modeling software.

And again, for any serious project you should never have tools such as Auto Setup or other tools that could interfere with your FBX files within your productive project.
Sandbox projects are there for this kind of things. A productive project needs to be sort of a sanctuary were nothing can mess it up

But hey, if one extra step, that is also a protective step, is too much for you then it's completely understandable.

I personally don't care about the version issue. I really care about Reallusion providing some custom shaders for Unity to be on-par with their CC shaders (skin, eyes, hair).
That would be the thing that would save time for everyone as we could have a real 1:1 quality result from CC to Unity (outside of Scene lighting of course)

Thanks Necka for your helpful suggestion. I didn't know if something like that would work, glad to know that it should. I am in fact targeting HDRP, and my reason for stating that we're roadblocked is that so far, essentially nothing has fully worked as documented by RL, and even worse is their total lack of response to any of our requests for clarity! Frankly, their complete lack of support for the Unity export pipeline is shameful! At the very least they could provide some documentation about how to complete an export for a character using the latest CC release, into some specified Unity version, in a reliable and repeatable way!! As far as I can tell, the only such documentation that's available has been provided by other users such as yourself!!
