      Kevin,

      Everything is at the right place, but.........
      I will have to wait till my new 17" powerbook (intel-based) arrives.

      Thanks for your info,

      greetings,
      Ton

        any thoughts on adding some type of joint strength? for example a table (legs attached with joints)when dropped from 10' for example, would cause the joints to break thus allowing the legs to go their seperate ways. 😄

        Breakable joints will be in SPIV.

          I found a new way to make a truster in SP:

          1. truster option (in UI)
          2. a magnet linked with a magnetic object
            and the new solution:
          3. a gear link between a motor and a slider. Motor is linked to a static object, slider is free.
            The model shows the three options together.

            I'm just wondering why are the SP joints stretching. Can you get rid of that? Or maybe could this be set for each joint separately? This stretching is sometimes helpfull but when you try to do things like chain links or tank tracks it's very annoying.

                Everything working amazing well... except I can't seem to rename controllers in the Mac version. I type a new name in the Inspector, but it doesn't seem to take. When I run the simulation, no sliders appear for motors or servos I attempted to rename.

                Is this a known bug?

                *** SEMI-WORKAROUND***

                I just created a new motor and used "slider('NEW NAME')" in the Controller field. That took... but it seems to only work once. I can't rename another motor, or (obviously) use the same name to run 2 motors off one slider.

                  Make sure you hit tab after you make edits in a text field in the inspector.
                  There is a known bug on the Mac where the web browser will not commit an edit in a text field unless you change the focus out of the field prior to changing the focus away from the web browser window.

                    That actually seems to work... about half the time, but it's much better than it was.

                    Thanks, WilleyKJ!

                      Sorry Phy but using the newton engine it's flat out impossible to have concave hulls. The staticmesh only works because it's... well, static. We're gonna have to live with using complex groups for complex shapes.

                      Well, I don't know much about physics engines and this kind of programming, but I've seen that the hull is geometry independent. So, I'm thinking: is it possible (for SP4, let's say) to make an algorithm that can generate a dynamic concave hull, by combining convex meshes for the same object? I don't know if multiple meshes are allowed to one object.

                        If I understand you correctly, that's already possible; but you have to manually make the convex meshes, and group them together.

                          Hmm, until now if you want to have interaction with a dynamic concave object, you had to combine more segment-objects in one group. Each part having its own convex hull. Instead I was thinking to virtualy create those subdivisions. The object to be one single solid and just the collision meshes to be more. On compex objects is really hard to group from smaller subdivisions.

                            Intelligently breaking a convex object into concave ones is really hard to do.
