      Hi again Dr Sassi,

      I'm having trouble baking dynamic clones as alembic.

      Since the last update of C4D where Bake as Alembic has an options icon next to it, I just cant bake clones and dynamic objects like I could before.

      These are the settings I've used:

      https://www.dropbox.com/scl/fi/rt03yc33ml7asdmh1hjvu/Cinema_4D_8vvVU8nuqW.jpg?rlkey=zw76oa9d6crn7p4aqssmcjqr4&dl=0

      But it almost always bakes an empty null.

      I've tried butting the clones in a connect object but that doesn't work either nor does making the cloned sphere editable.

      Maybe it doesn't like the fact that I have rigid and cloth objects?

      It also wont work if I cache the dynamics first

      Any ideas?

      Here's my file: https://we.tl/t-6cSZ86ZN41

      Thanks again!

        Hi MaverickMongoose,

        Thank you very much for the files.

        Sorry that you have some trouble.

        (Do you use the Cache Tab entry to turn it to an abc. I'm not clear what you meant with the Icon next to it.)

        I have tested your file.
        Since the Selected Only was on, I selected all objects.

        One time with the connect, one time without.
        I also exported it.
        Each time, all went fine.
        I have attached the results.

        Since I have no option to recreate the problem, please check with the support,
        https://www.maxon.net/en/support-center

        I checked the usual source, but no one has had that problem.

        Fingers crossed, there is an easy fix.

        My best wishes

          Cheers, it still doesnt work for me, are you using the latest C4D where they changed the alembic feature? If you right click and bake as alembic it now has an options Icon which wasn't there before

          I tried another scene and still get issues, here's a screen recording: https://www.dropbox.com/scl/fi/nbx9ystkpkxq4xwk000xr/Cinema_4D_l6a6F52cUx.mp4?rlkey=a11cb0f2bz4rzbtcd9zma9hvo&dl=0

          I've contacted Maxon support so I guess ill see what they say.

          Do you know if its possible to revert to an older version of c4d from the maxon app?

            Hi MaverickMongoose,

            I used 2024.5.1 on an M1 Mac.

            The Alembic Exporter was 1.8.4, for example, in 2023.2.2. The Selection setting is now by default and that is the case in 2024.5.1, which is also 1.8.4. The interface nor the function has changed.

            Please check this video below:

            https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2024_Clips_DRS/20240814_2024-5-1_Alembic_184.mp4

            If that doesn't work, please check with tech Support.

            For anything else, I'm happy to look into the morning (perhaps the afternoon tomorrow, as the morning is filled with meetings). [Pacific Time Zone].

            Anyway, when I select only the Cloner, I get no result, going by the settings that I see in the interface, which are, by the way, the same as you get.

            Fingers crossed, it is as simple as the selection.

            Cheers

              Confirming the issue is there also for me, 2024.5.1 has worked fine before. The cloner object gives an empty null when exporting to Alembic.

              It seems to be a bug, when cloner mode is set to 'Object', when selecting 'Grid' or 'Radial' then it bakes correctly. It's fixed in 2025.0.0 fortunately.
