Round table cloth anywhere?

I'm after a round table cloth to use for a restaurant round table. It should be either dForce enabled, or able to apply a dForce modifier to sim.

Thanks in advance.

    Y scaled down sphere cut in half using the Geometry editor wouldn't work?

    Oh, never thought of that.

    Don't forget to use a high Divisions value so the Dynamic dForce modifier will work. (I always end up using 1 and wondering why dForce isn't working.)

    It doesn't seem to work for me, I'll have to try something else.

    What part isn't working? What happened when you tried? Try a plane with a circular opacity map to get more even mesh quads for dForcing. You could use the Geometry Editor capability to rotate triangulation of selected polygons to improve draping smoothness.

    while I haven't tried a tablecloth, I have made many circular skirts from edited DAZ sphere primitives

    you cannot edit it after making it a dynamic object though, if you do, you will need to remove that and reapply

    and yes, load the primitive with lots of sections and divisions

    It might be helpful if you also posted the before primitive in wire view.

    It is just a Daz primitive plane. I think I created it 2 or 3 Meters on a side and 100 divisions. I rotated the triangulation of two quadrants so all quadrant triangulation aimed toward a plane corner. There was a Daz tutorial on that technique when dForce was introduced. I can't add any images tonight. My computer is shut down and I have only my phone.

    Thank you for all your suggestions, I figured it out.

    Here is a top view screenshot of the primitive plane with my circular opacity map, a blue viewport background, and the Triangulation Wireframe Opacity increased in Draw Settings.

    Did the triangles help it drape? Otherwise it seems to be a step not altogether needed. Always wanting to learn. Regards, Richard.

    The way the triangles is orientated can help it drape better, more smoothly.

    But this is a fairly dense mesh, so noy sure how much it would change.

    Traingulating can help, but you can control how DS triangulates to mimic the way that the two diagonally oposite quadrants have the same direction of split and the adjacent quadrants the opposite by using the right-click>Geometry Editing>Rotate Triangulation... command with the Geoemtry Editor on the selsected quadrants, which avoids doubling the working polygon count.

    It might not add much for this density. I don't have any evidence one way of the other. I didn't try without the triangulation rotation, because with it was my best chance for success. It is very easy to do the triangulation rotation on a plane like this, so I just did it.
