Hi a1315701643 Thanks for your feedback. According to your picture, both slider "V_Open" and "Jaw Open" are bone offset morph slider. Currently CC just supports mesh morph when exporting fbx. If you need the open mouth morph slider, try to export fbx with ticking "Mouth Open as Morph" checkbox in Advanced Settings (ref: image), then you will find "Merged_Open_Mouth" slider. Please feel free to contact us if any. Tina
