      Hi!

      I have a simple object with a simple rig and painted weight. It works fine in C4D. I can move the top of the cone with the proper joint as it's in the top of the picture.
      But if I export it to FBX and open C4D or other program like Unreal the weight is messed up.
      What do I do wrong?

      here is the shot

      Thanks!!!

        Would you mind sharing the c4d file here so I can take a look?

        All the best

            Hi wine-news,

            Thanks for the file.

            The main rule for anything joint-based is that each point on the mesh needs a total of 100.00% Weighting from all Joints. Not more, not less. While some export options limit the number of Joints "working on a point."
            Why 100%?
            If you move the root and the points have more than 100%, it moves faster; if it has less, it moves slower. When a point has a summary of 100%, all is fine.

            In the file from above, only one joint influenced the mesh. At the same time, most points were below 100%.

            Please check the file: (Press Play)

            Perhaps even export your FBX and reload it to see if it works for you.

            Cheers
