      Hi AlexC,

      Thanks for using dropbox.

      Here is your file back
      https://projectfiles.maxon.net/Cineversity_Forum_Support/2024_PROJECTS_DRS/20241001_CV4_2025_drs_24_SItf_01.c4d.zip

      The hole in the tree was smaller than the Ropes' radius. I also have set the Gravity to 1%.

      The file is cached; perhaps export it as Alembic and reimport it so you can change the timing to your needs.

      Let me know if that is working for you.

      Cheers

        Hello Sassi

        Thanks for this! Great to see the file!

        Do you know how I could get this work inside a cloner? I tired with a connect object, but no luck...

        Thanks!

          Thank you very much, AlexC, for the reply.

          Would the Alembic route work? So the Dynamic is "baked".

          Here, the Blend option in the Cloner is on, and the Timing is set in one abc instance differently. This is a suggestion; the abc file can be used alone under a Cloner.

          All the best

            Hello Sassi

            Alembic wouldn't work because I need each rope to fall differently based on the rotation of a set of these trees. But its actually ok, I need to place them very precisely so I will be doing it by hand, there are not that many to place.

            Thanks again!!

              Hi AlexC.,

              Particles work now with Cloners, as you had asked a while back, but Simulations with Ropes and a Collider in one seem to have problems 😉

              This means we need to make Cinema 4D think it is one Rope. In other words, the split between Rope and Collider is required. That is not difficult, but it requires a central source to move them around, and that needs the setup that matches the Rope and the Collider (Tree) after Cloning. See file …_21.c4d

              I tested it with a Random Effector (Pos/Rot) and it works. Please make sure to use ONLY the Matrix is changed.

              Enjoy.

                Got it, understood. Thanks Sassi! That makes sense.

                  Hello again!
                  I just tried this with the setup I'm trying to create, and I'm pretty sure I followed your method, but somehow the dynamics don't seem to want to kick in.
                  Is there something wrong in my setup?

                    Hi AlexC,

                    Thank you very much for the file.

                    I have changed the radius of the Rope
                    I moved the Rope Tag up to the Connect
                    Then, reduced the gravity

                    Please check if that works for you now.

                        It was a pleasure to explore.
