Disable Horizontal Flip: Check to disable horizontal flip of motion. After changing this option press Calibrate position to calibrate.

Calibrate Position: Press to calibrate the position by current user position captured by web camera.

Voice based motion when webcam not used: When image based head tracking is not used, avatar moves automatically by voice input.

Eye Look Target: Select where the character look to. Available in Streaming tab. Select Mouse to makes the character look at the orientation mouse pointer exists. Select Fixed to fix head motion except face tracking. User is similar to Fixed, but different when the character body does not face straight to the monitor, by Free Camera Mode. In this case User makes the character looks head to straight to monitor (in other word, keeps to look you).

Move eyes during facial expression applied: Turn on to move eyes during Word to Motion

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.


Disable BlendShape Interpolation: This option is available from v2.0.4. When turn 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 character will become always smile, but some character’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.
