We created an app with ARKit face tracking and the blend shapes would come consistently in this order -
“eyeBlink_R”,
“eyeWide_R”,
“mouthLowerDown_L”,
“eyeLookDown_R”,
“cheekSquint_L”,
“mouthDimple_R”,
“browInnerUp”,
“eyeLookIn_L”,
“mouthPress_L”,
“mouthStretch_R”,
“browDown_L”,
“mouthFunnel”,
“noseSneer_L”,
“eyeLookOut_L”,
“eyeLookIn_R”,
“mouthLowerDown_R”,
“browOuterUp_R”,
“mouthLeft”,
“cheekSquint_R”,
“jawOpen”,
“eyeBlink_L”,
“jawForward”,
“mouthPress_R”,
“noseSneer_R”,
“jawRight”,
“mouthShrugLower”,
“eyeSquint_L”,
“eyeLookOut_R”,
“mouthFrown_L”,
“cheekPuff”,
“mouthStretch_L”,
“tongueOut”,
“mouthRollLower”,
“mouthUpperUp_R”,
“mouthShrugUpper”,
“eyeSquint_R”,
“mouthSmile_L”,
“eyeLookDown_L”,
“eyeWide_L”,
“mouthClose”,
“jawLeft”,
“mouthDimple_L”,
“mouthFrown_R”,
“mouthPucker”,
“mouthRight”,
“browDown_R”,
“eyeLookUp_L”,
“mouthSmile_R”,
“mouthUpperUp_L”,
“browOuterUp_L”,
“mouthRollUpper”,
“eyeLookUp_R”
If you update the iOS to 13 and then run our app it appears to be in a slightly different order?
Or at least the mouthsmile_L blendshape seems to be triggered by something else and we can’t work out what it is.
