      and here is the model, if you want to play...
      The mesh count of the cloth can be increased by copying the elements accordingly and adjusting the numbering of the matrix ...
      Two very interesting techniques have been used: self-linking groups and the creation of a surface following the simulation.
      The model is a little bit modified by me (sorry, don't know the name of the author and can't find it on 3D-warehouse, only copies...)
      If this could be translated for MS Physics one day - Hallelujah β˜€

        Actually this can be done with MSPhysics. All this does is creates a bunch of speres linked by BallAndSocket joints. Then it uses a script to move cloth vertices to new position. This is artificial cloth and has its downsides, primarily the performance. But I can modify that small script for compatibility with MSPhysics.

            So it might work with msphysics?

            I hope as I don't have access to su 2016 anymore.

              a proof of concept to creating like "Marvelous Designer " plugin perhaps. Are we still decades away from there?

                Here is the proof!

                I intend of writing a new plugin for this kind of stuff.

                  That would be very very cool Anton!

                  It would make cloth creating a lot easier.
                  Just create a flat cloth, add a nice texture, animate the cloth onto a chair, stop the animatin, make small adjustments with artisan or like - and render.

                  Can we set the resolution of the cloth?

                  Thanks

                    Yes, Jorgensen,

                    The resolution is dependent on the number of vertices of your cloth or any other deformable mesh. If you have a plane made up of many vertices, the the number of bending vertices will be as much. Before getting it fully working, I need to make the faces in between the vertices to be collidable as well. That way things in between, such as the edges of the table shown in the video, won't intersect the cloth. I also need to make different constraints for the nodes that will allow the deformable mesh to stretch and unbend, such as for making a tire, a gummybear, or a sofa, or anything squishy.

                    I'm still trying to decide whether to include it in the upcoming release of MSPhysics or write a new plugin that will specifically focus on soft body simulations.

                    Regards,
                    Anton

                        hi anton

                        my personal thought - release it as quick as possible πŸ˜„

                        but if i was you, i would design it as a "cloth plugin" for sketchup, that makes it very clear what the plugin is used for - and consider make it a "pay for" plugin - good plugins takes time to develop and i'm sure people will pay, if the quality is there πŸ˜„

                        thanks

                          Do what ever is easiest for you development wise.
                          A cloth simulator would be awesome.
                          Making it work with Thomthoms subD would be prefered.

                          Don't think too long.
                          Just do it! πŸ‘ πŸ˜„

                            I vote for a stand alone cloth simulator, great work by the way.

                              Great examples in your video, Anton! And it seams to work in MSPhysics.
                              A simple variant for MSPhysics would also be welcome.
                              This would make moving objects made of flexible materials more natural.
                              The problem of interpenetration of the partial surfaces could be solved temporarily with larger hidden body parts.

                                Definitely a separate cloth simulator, pretty please!

                                Save the Earth, it's the only planet with chocolate.

                                  Thank you all for your suggestions! Now suggestions for the name of the plugin and some upfront ideas would be great.

                                  Right now I'm thinking of naming it, SoftWorks.

                                  The plugin will have a UI for controlling the selected deformable groups' mass, stiffness and linear/angular acceleration/damper.

                                  There will also be a toolbar.

                                  One toolbar button will allow dropping/simulating the selected or all the deformable bodies until a stop button is pressed, which will freeze​ all/selected in place.

                                  Another button will allow resetting the original placement of all/selected bodies.

                                  And another button will allow toggling the UI.

                                  Another two will allow adding Fixed and Slider constraints in places. The touching cloth will automatically will be connected to the constraints.

                                  As for the back ground, all other non-ignored visible groups/components will act as static/movable solid bodies.

                                  There will also be options for exporting animations.

                                  These are the ideas for now. Suggestions that will guide me in the right way would be nice.

                                  Thanks!

                                      There are several firms in the world with the name "Softworks"...
                                      Regarding the functions of the plugin you are on the right way.
                                      It sounds like a little bit of a baby of MSPhysics outside of the physics world.
                                      Please don't forget the mother... πŸ˜‰

                                        Hi Anton

                                        I think you should think in search therms / what it does - use words that people search for - i searched for "cloth simulator", so that would be my suggestion (even though is does more).

                                        Will I be possible to pick the cloth itself - and deform it?

                                        Can you talk about an estimated development time? Like one week or two months?
                                        (I know it can be difficult talking about that).

                                        Thanks

                                          It would be cool if it could have a virtual thickness setting for simulating thicker stuff.
                                          And maybe a setting so that it could use let's say every other or third vertices of a dense mesh to speed up simulation.
                                          My only name suggestion so far are Draper or ClothWorks.
