      Hi!

      Quick question: with rigid bodies in The Simulation System I can't find an option that calculates the entire chain of child objects as compound collision shape. This exist with Bullet - is there no way to achieve the same result?

        Hi history-growth,

        I assume you have the "Hierarchy Merge Level" in mind:

        Let me know if I got your question correctly.

        All the best

          Hi Sassi!

          Yes and no. As I understand Hierarchy Merge Level it seems as the right thing - take next level of objects into account for the simulation.
          But with the Armchair 01 from the asset library it generates no result at all even with this option set to 3.
          If I do put the object inside a Connect the Simulation does work but the physics is not realistic - the same setup with Bullet generates a much more realistic look.

            Thank you, history-growth,

            Please have a look here:

            My understanding is that these levels target MoGraph hierarchies.
