I followed all the steps for creating the morph targets.

I created the list and assigned the facial expression based on the Morpher names and it's completely broken.


Morph targets are not where they are assigned on the exported FBX. The wrong morph target is trigged when I import it into CC4.



This is extremely frustrating as I had to sculpt all the targets and then resculpt them because the imported FBX only works with meshing within the scene, so imported resculpted meshes break the rig.

Also, I asked previously if the Eyebrows need to be rigged to the head or can be driven separately I got no response. Is there an actual tech team I can talk to about these issues?

The Support channel sends me right back here to ask the community for answers to basic questions. So when I ask a basic question like
"Can the eyebrows be driven by the facial animation profile or do they need to be attached to the facial profile expressions" I'm under the impression it's a basic question. However, seeing that no one has responded it would appear that is a more technical question that I will have to make a ticket to support to answer.

Custom eyebrows created from an accessory by clicking "Create Hair, Brows, Beard" button and selecting eyebrows. There is no need to do anything else. It would follow expressions.

I am not sure about your workflow, but the viseme list is missing tongue morphs. If you are importing a sequence, it might shuffle the order.

This is a "Standard" profile expression sequence map:

[Viseme]
0 = V_None
1 = V_Open
2 = V_Explosive
3 = V_Dental_Lip
4 = V_Tight_O
5 = V_Tight
6 = V_Wide
7 = V_Affricate
8 = V_Lip_Open
9 = V_Tongue_up
10 = V_Tongue_Raise
11 = V_Tongue_Out
12 = V_Tongue_Narrow
13 = V_Tongue_Lower
14 = V_Tongue_Curl_U
15 = V_Tongue_Curl_D


[Expression]
16 = Brow_Raise_Inner_L
17 = Brow_Raise_Inner_R
18 = Brow_Raise_Outer_L
19 = Brow_Raise_Outer_R
20 = Brow_Drop_L
21 = Brow_Drop_R
22 = Eye_Blink_L
23 = Eye_Blink_R
24 = Eye_Squint_L
25 = Eye_Squint_R
26 = Eye_Wide_L
27 = Eye_Wide_R
28 = Eye_L_Look_L
29 = Eye_R_Look_L
30 = Eye_L_Look_R
31 = Eye_R_Look_R
32 = Eye_L_Look_Up
33 = Eye_R_Look_Up
34 = Eye_L_Look_Down
35 = Eye_R_Look_Down
36 = Nose_Sneer_L
37 = Nose_Sneer_R
38 = Cheek_Raise_L
39 = Cheek_Raise_R
40 = Cheek_Puff_L
41 = Cheek_Puff_R
42 = Mouth_Smile_L
43 = Mouth_Smile_R

Thank you! I appreciate that. The bad thing about the exported for Max is that it places 30 frames between keys so the list you provided only tells me the order but not the frame count.

Ok so maybe the exporter is broken. Should I place the Keyframes one after the other? Should there only be a total of 90 keyframes? Maybe that's why it's breaking in CC4.

I don't have a transfer Skin weights option for the eyebrows.

I do not work with 3DS nor C4D. Only with Blender.
But forget about your custom character for a moment.
Create successful workflow for Export/Import blend-shapes to/from your app with Neutral base (exporting with sequence from CC and importing back from FBX through the app of your choice).
Then, when you successfully tested the routine, you may compare morphs order, timeline, export settings.. etc, etc with your character to see where the deficiency is.


For eyebrows, again you have to use "Create Hair, Brows, Beard" button (not Transfer skin Weight). There is an eyebrow option there.

I have identified the issue with the facial profile for Max. The profile exports with a list of expressions in the morph target channel that do not match the list provided when exporting. Additionally, Max places 30 keyframes between morph keys, causing confusion with the frame sequence. I had to reorganize everything to match the list and was able to successfully create facial expressions. However, now I am experiencing an issue with the accu-rig where the upper mouth verts are protruding, creating a spike-like appearance on the upper lip. I attempted to fix this by painting skin weights, but it did not work. It seems as though CC4 is assuming the model was modeled in this way It sure wasn't. (Include image here)
