Paint skin weights for creases

Note Reflection is disabled for the Paint Skin Weights Tool. Skin > Edit Smooth Skin > Mirror Skin Weights can be used as an alternative method to do reflection of the skin weights.

To paint creasing effects

1. Select smooth shaded display mode (hotkey: press 5).
2. Select the cylinder.
3. Select Skin > Edit Smooth Skin > Paint Skin Weights Tool > .

(For more information, see Painting smooth skin point weights.)

4. In the Tool Settings window, the Influence section should be displayed. For more information, see Skin > Edit Smooth Skin > Paint Skin Weights Tool.
5. Note the Transform box.

The Transform box lists the names all the joints.

6. Click on a joint name. For example, click joint3.

In the scene, the shading indicates the joint’s influence. The whiter the color, the greater the influence of the joint.

Note how the joint’s influence fades into black as the distance from the joint increases.

7. In the Influence box, click on another joint name. For example, click joint4.

Again, note how the joint’s influence fades into black as the distance from the joint increases. Also note how the joints gradually influence the bending and creasing.

8. Check the influence of one more of the joints. For example, check the influence of joint2.

Joint2 mainly influences the skin below the bend, but does provides some gradual influence in the bend area.

Similarly, joints above the bend (for example, joint5) also gradually influence the deformation in the bend area.

Now you will edit the influence of the joints to get a sharper creasing effect. You can do this by increasing how the joints nearest the bend influence the creasing, and lessening how joints further from the bend influence the creasing.

9. Use the Paint Skin Weights Tool to paint how the joints influence creasing.

The brush provides an intuitive way to change the influence of the joints. Use the brush’s Add operation to increase the influence of nearby joints, and use the Scale operation to decrease the influence of further joints. Use the Smooth operation to smooth out the influences of the joints. For more information on using paint tools, see Artisan Tool Settings editor in the Artisan guide.

Try to get the creasing to look something like the following, which is closer to what you might want for an elbow deformation.

Experiment with using the brush. With just a little experimentation, you can quickly become proficient at painting the skin point weights of joints.
