I tested something out last night. I had a DAZ Character in my Iclone library. I loaded it and noticed that you can't convert its materials to the Digital Human shader. Does this mean that the new shader will not be available to custom content? It's kind of a let down if you can only apply it to CC3 characters. I hope that's not the case. If Reallusion were to at least create a guide to creating the right maps for these shaders for custom content it would be better than not having it at all for any of your custom content.
I'd love to be able to bring my own figures into Iclone and take full advantage of this, but it looks like something that is only available for Character Creator 3 content. I hope this is not the case forever.
