Hand Setting (Beta) Detailed Explanation

After upgrading the Udcap Driver software to version V0.1.7.0, please refer to this document.

The Hand Setting page allows you to adjust the hand movement performance of your avatar in VRChat.

Each finger has two adjustable points: Point 1 and Point 2.

Point 2

Point 2 adjusts one parameter: the Pitch value.

The bending range of the VRChat avatar's fingers is determined by the model itself, so we cannot adjust the minimum or maximum degree of bend, only the balance.

The Pitch value controls the finger's degree of bending.

Pitch - Balance Value: Dragging to the left means the finger bends slowly at first and then faster; dragging to the right means the finger bends faster at first and then slower.Example: If you find the tip of your VRChat avatar's index finger isn't bending responsively enough, you can adjust the Balance value for Index Finger Point 1 to the right. Conversely, adjust it to the left if the opposite is true.

Point 1

Point 1 adjusts two parameters: Pitch value and Yaw value.

The Pitch value is adjusted as described above.

The Yaw value controls the degree to which the finger spreads outward (abduction/adduction).

Yaw - Min Output: Adjusts the angle of the finger when the hand is closed/relaxed.

Example: If you find your VRChat avatar's index finger leans too much to the right when the hand is closed, adjust the Yaw - Min Output for Index Finger Point 1 to the left. Conversely, adjust it to the right if the opposite is true.

Yaw - Max Output: Adjusts the angle of the finger when the hand is fully spread open.

Example: If you find the spread angle of your VRChat avatar's index finger is too small when the hand is open, adjust the Yaw - Max Output for Index Finger Point 1 to the right. Conversely, adjust it to the left if the opposite is true.

Yaw - Balance Value: Dragging to the left means the finger spreads open slowly at first and then faster; dragging to the right means the finger spreads open faster at first and then slower.

Example: If you find your VRChat avatar's index finger isn't spreading responsively enough, adjust the Yaw - Balance value for Index Finger Point 1 to the right. Conversely, adjust it to the left if the opposite is true.

Recommended Adjustment Scheme

Based on the default settings, we provide a set of recommended adjustments for users' reference.

Note: The parameters in this scheme are the same for both the left and right hands.

1. Thumb 1 - Pitch - Balance: 90% (Increases thumb bending responsiveness)

1. Index Finger 1 - Yaw - Min Output Value: 5, Max Output Value: 35 (Provides a more natural look for the index finger when the hand is closed/relaxed and when spread open)

1. Middle Finger 1 - Yaw - Offset: -5 (Provides a more natural look for the middle finger when the hand is closed/relaxed and when spread open)

1. Ring Finger 1 - Yaw - Max Output Value: 20 (Provides a more natural look for the ring finger when the hand is closed/relaxed and when spread open)

1. Little Finger 1 - Yaw - Min Output Value: -5, Balance: 10% (Provides a more natural look for the little finger when the hand is closed/relaxed and when spread open)
