  You need a different mappings for visemes in Unity. For example:

  **Step 1: Export Genesis 3 Male from Daz Studio**
  1. In **Daz Studio**, select your Genesis 3 Male character.
  2. Go to **File → Export** and choose **FBX** format.
  3. In the FBX export options:
     - **Morphs**: Enable *Export Morphs*.
     - Add the **viseme-related morphs** (e.g., `PHMmm`, `PHMaa`, `PHMee`, etc.).
     - Set **FBX 2014/2016** for best Unity compatibility.
  4. Export the file.

  **Step 2: Import into Unity**
  1. Drag the exported FBX into Unity.
  2. In the **Inspector**, select the FBX → **Rig** tab → set **Animation Type** to *Humanoid*.
  3. In the **Model** tab, check **Import BlendShapes**.
  4. Apply changes.

  **Step 3: Map Daz Morphs to Unity Visemes**
  Unity uses **12 visemes** for lip-sync
  (e.g., `sil`, `PP`, `FF`, `TH`, `DD`, `kk`, `CH`, `SS`, `nn`, `RR`, `aa`, `E`, `ih`, `oh`, `ou`).

  Daz Genesis 3 morphs have names like:
  - `PHMaa` → `aa`
  - `PHMee` → `E`
  - `PHMoo` → `oh`
  - `PHMpp` → `PP`
  - `PHMff` → `FF`

  You need a **mapping dictionary** like this:

  private Dictionary<string, string> dazToUnityVisemeMap = new Dictionary<string, string>()
  {
      {"PHMaa", "aa"},
      {"PHMee", "E"},
      {"PHMih", "ih"},
      {"PHMoo", "oh"},
      {"PHMou", "ou"},
      {"PHMpp", "PP"},
      {"PHMff", "FF"},
      {"PHMth", "TH"},
      {"PHMdd", "DD"},
      {"PHMkk", "kk"},
      {"PHMch", "CH"},
      {"PHMss", "SS"},
      {"PHMnn", "nn"},
      {"PHMrr", "RR"}
  };

  Use at your own risk, if you wish.
  To test it in Unity try:
  1. Attach the script below to your character GameObject.
  2. Assign the **SkinnedMeshRenderer** (usually under the FBX hierarchy).
  3. Call `SetViseme("aa", 100f);` to test.

  using UnityEngine;
  using System.Collections.Generic;

  public class DazToUnityVisemeMapper : MonoBehaviour
  {
      public SkinnedMeshRenderer characterMesh;

      private Dictionary<string, string> dazToUnityVisemeMap = new Dictionary<string, string>()
      {
          {"PHMaa", "aa"},
          {"PHMee", "E"},
          {"PHMih", "ih"},
          {"PHMoo", "oh"},
          {"PHMou", "ou"},
          {"PHMpp", "PP"},
          {"PHMff", "FF"},
          {"PHMth", "TH"},
          {"PHMdd", "DD"},
          {"PHMkk", "kk"},
          {"PHMch", "CH"},
          {"PHMss", "SS"},
          {"PHMnn", "nn"},
          {"PHMrr", "RR"}
      };

      private Dictionary<string, int> blendShapeIndices = new Dictionary<string, int>();

      void Start()
      {
          if (characterMesh == null)
          {
              Debug.LogError("Assign the SkinnedMeshRenderer in the inspector.");
              return;
          }

          // Cache blendshape indices
          for (int i = 0; i < characterMesh.sharedMesh.blendShapeCount; i++)
          {
              string shapeName = characterMesh.sharedMesh.GetBlendShapeName(i);
              if (dazToUnityVisemeMap.ContainsKey(shapeName))
              {
                  blendShapeIndices[dazToUnityVisemeMap[shapeName]] = i;
              }
          }
      }

      public void SetViseme(string viseme, float weight)
      {
          if (blendShapeIndices.ContainsKey(viseme))
          {
              characterMesh.SetBlendShapeWeight(blendShapeIndices[viseme], weight);
          }
          else
          {
              Debug.LogWarning($"Viseme {viseme} not found in blendshapes.");
          }
      }
  }
