Face animation with bones (Daz3D to UE4)

Victoria 8 expressions (eCTRL) exported from daz3d as animation, one expression per frame. Imported in Unreal Engine 4, played at 10% speed. All animated with bones, no morph targets.

We made an animation in Daz3D that has exactly one eCTRL attribute enabled every frame. This was done using a script, key was set to linear.

Then we exported the animation with all morphs baked and as usual X/Y/ZRotations disabled in morph rules (Daz sometimes thinks that rotations should be baked as morphs, therefore ignoring those “morphs” in the list or rules solves the issue)

Resulting animation uses only face bones, no morph targets. It should be possible to export eJCM morphs too, but it looks already good like that.

UE4 don’t support more than 8 influences. Victoria 8 has max 8 influences almost everywhere, only couple of vertices have more influences (on the cheeks).

Importing in UE4 and playing at 10% speed gives the result above.

Next step is to split that to poses.

Also, look at those UE4 eyes from photorealistic character sample! Has to write more about it.
