Eye Motion Scale[%]: Set how eye (eye bone) moves by mouse gaze, or by ExTracker. Recommend default (100%) for VRoid model. If avatar eyes motion is too small, try larger value.

BlendShape

Disable BlendShape Interpolation: When turned on, then facial interpolation process for Word to Motion and Face Switch are disabled, and facial expression always switches immediately.

Default Fun Blend Shape [%]: Specifies the default fun expression rate. As the value increases the avatar will become always smile, but some avatar’s facial expression will be unnatural when combined to blink or other face motions. In those cases, decrease the value.

Default Face BlendShape: In most case you should leave it empty. If your model needs some default expression to be applied, then select the BlendShape clip. Notice that the selected blendshape and BLINK_L, BLINK_R, lipsync, and perfect sync will run at the same time.

Offset BlendShape: In most case you should leave it empty. If your model has some BlendShapeClip which must be applied always to adjust body or face shape, then select it.
