Hey Guys! I just figured out a way to make the Chinese Frog on the Cheongsam!

BTW, the Chinese Frog is this one ↓

To Make a Chinese Frog, you should do these steps:

1.Make a rectangle pattern that is big enough, and make it flatted on the ground.

2. Lower the particle distance of this pattern to 1 and use internal polygon tool to make a shape like below.

3.Freeze the pattern.

4.Make a slice pattern which width is the same as the internal line.

5.Sew the slice to the rectangle pattern.

6.Lower the particle distance of the slice to 1.Lower the Add'l Thickness-Colision to 1. Make the layer to 1. 

7.Select the slice in 3D window and choose Superimpose(Side).Then use Gizmo to arrange it above the rectangle.Then simulate.

8.Add the Add'l thickness-Rendering of the silce to 5 ( It depends on your own choice).After that, make the layer to 0.

9.Copy and paste/mirror paste the internal lines beside the original one in the 2D window and same as the slice pattern but in 3D window.And make the sewing lines.

10.Import a pearl OBJ file (You can make it from 3DSMAX) to the middle of the patterns.Be careful to use glue tool to make the obj file to the silces, not to the rectangle.

11.Delete the rectangle and export the Frog as an OBJ file.
