Holy Shit! Pay this guy reallusion. He has made cc3 characters actually worth it in unity.

Is there a way to enable tesselation and displacement maps yet?

Per the previous page, have you tried this (bake and then use hdrp/tesselation phong shader):

Fantastic! Thank you.

Just had a go - image is from within Unity - Brand New to reallusion and in 3 hours got it in. (There's maybe a small issue with the brow lines? But not to worried about it.)
The URp one would be great too.

The results are impressive. I'm running into a problem with lip sync. In the timeline, lip sync works good. When I hit play (runtime), the lip sync is off. Anyone else have this problem?

Are you starting the audio as soon as you hit play? You need to wait until everything has finished loading before trying to synchronise anything.

Ahh, I see what you mean. I was starting audio as soon as I hit play. I had to advance to about 25 frames for it to stay synced after hitting play. I'm wondering if there is a way to warm-up after hitting play and before it actually begins playing. Otherwise I will have to make sure all audio is advanced at least 25 frames on the Timeline.

Other than starting it from a script, you could start with the character intitially disabled. Then enable when you're ready.
