      Hello! (Sorry I still only have permission to post in "Site Issues".. please feel free to move this post.)

      I have some squiggly cloth sim elements using RSMGIDRatioColor in the RS shader to assign a gradient of colors to a bunch of cloned objects. It works as expected, until...

      I add final touches such as SubD or or Cloth Surface to smooth out the geometry, then it seems to override the mograph index and everything gets set to one color, which seems to be the first color in the gradient.

      This seems like a common problem, and the solutions all seem to be "find a different way to do it" 😆 Is there a workaround that I am not aware of?

      Sorry, I'd post pictures if I could, but my network restricts that. Hopefully I've described it well enough. Thank you for any insight!

          I will make a ticket! And thank you for the project.

          As for my issue, take that array you made and put into a SubD and/or a Cloth Surface and you will see my issue. It changes to one color. I need to smooth out my surfaces and add thickness via Sub D and Cloth Surface.

            NOTE: I can get it to kind of work if I use RSGeomIDColor instead of the mograph ID, but then the colors end up randomized, which is not the look I require.

              Thank you very much, Harry, for the ticket.
              I'm not running the Site Issue forum, and I have no access to customer data. We take privacy here pretty seriously, way above what the law asks us to do. I wouldn't want to have access even.
              So, I do not check here often in the Site issue forum.

              The simple answer is that generators, like the SDD, generate new Geometry, and that doesn't include any MoGraph ID.

              An alternative could be:
