4. Check for Morph Targets (Shape Keys)

• If no shape keys exist, they must be manually created.

5. Create an "A" Mouth Shape Key

• Select the face.

• Click the "+" icon twice in the Shape Keys section.

• Rename the new key to fcl_MTH_A.

• Increase the Value slider to 1.

• Switch to Edit Mode.

• Hide the armature for better visibility (toggle the eye icon in the Outliner).

• Enable Soft Selection Mode (top menu bar, circular icon, select "Connected Only").

• Adjust the mouth:

  • Select the upper lip and move it up.

  • Select the lower lip and move it down.

  • Adjust the surrounding vertices to refine the shape.

• Hide teeth/tongue if necessary using Ctrl + L to select linked vertices, then move them.

• Switch back to Object Mode and test the slider.

6. Create an "O" Mouth Shape Key

• Add another shape key and rename it fcl_MTH_O.

• Set the previous key’s Value to 0.

• Increase the Value of the new key to 1.

• Switch to Edit Mode and adjust:

  • Move lips to form a circular "O" shape.

  • Hide teeth/tongue if needed.

• Return to Object Mode and test the shape key.

7. Export the VRM

8. Test in Otherhalf

• Import the VRM into Otherhalf.

• Ensure morph targets function properly.
