In the same way as explained before use the face tool to create faces for the body surface.
Don't worry if it doesn't look great, just move on.
Legs
1. We would like to connect these two surfaces, but since the size of the edge of the legs and the size of the body surface are very different, it is not possible to connect them very neatly by stretching the surfaces as they are.
2. You can divide the surface of the body first, but MarbleCLAY has the feature that you can create the surface and divide the surface at the same time, so use this function to divide the body while creating the surface.
3. Select the face face/UV weld(3) tool and click (1)->(2). An edges is generated.
4. Next, click the vertex of (1), and the edge of (2).
5. The body faces are divided into triangular and quadrangular faces.
At this time, the edge sandwiched between the two faces is displayed as a dotted line, and this edge is called a semi-determined edge in MarbleCLAY.
6. Next, continuously Clicked with (1) -> (2)
7. The semi-determined edge created earlier disappears and a new square face is generated.
(The face connected to the edge of (2) is newly divided into a triangular face and a quadrangular face, and another semi-determined edge is generated.)
8. Continue to divide the body polygons in the same way.
