@honzu : I assume you use the comma as decimal separator in Windows. Also in France, the decimal separator is a comma, but since a long time, I change Windows settings to put the decimal separator as a point. When I develop a program, as I do not know what is the decimal separator for the people who use this program, I force the decimal separator as a point. Obviously there is a problem that I have not seen and I'm going to experiment by putting back my original decimal separator and find a way to solve this problem.

@ErickL88 : You raise a very interesting problem on which I have not given enough information. I will, first of all, give the reason for the problem. By default, VWD is made to work with conforming clothes, that is, the program uses a stiffening by Neighborhood. The default distance for this Neighborhood is 1 for the clothes, this is to say that two vertices that are at a distance less than or equal to 1 will have a relationship by spring. In the example that you show, the minimum distance between the closest vertices of the two legs is less than or equal to 1. To know the distance between two vertices, you can select a vertex using the "SHIFT" key and in the "Vertices tools" tab, click the "Neighbours" button with a value of 1. All selected vertices are at a distance less than or equal to 1 of the selected vertex. I do not know the pants that you used, but it seems that these pants could be dynamic. A dynamic object have a continuous mesh, ie all the vertices of the mesh are connected. To determine if an object is dynamic, you can use the previous method, ie selected a single vertex with the "SHIFT" key and press the "Element" button, if, after performing this function, all vertices of the mesh are selected, this object is dynamic. I return to the error, if your pants are dynamic, you can use a stiffening by extension at the time of creation. This solution will solve your bonding problem. If your pants are conforming, ie if some items fall during the simulation because they are not linked to other vertices, there is still a solution. You can use a stiffening by extension when creating the cloth and then, you can use a stiffening by Neighborhood, locally by selecting some vertices. I was particularly long, but I think I have not given enough information about all the work that may be necessary to make on a dress or hair to achieve the desired result. VWD have many parameters (and it is not finished) and I can assure you that all these parameters are useful.

I want to really make tutorials videos to show how work all the parameters of VWD. My poor English is still too weak to make these videos in the language of Shakespeare. But I progress slowly .....
