    If I have a single mesh object and I would like to apply different colors to various parts but would like the colors to blend where they meet. Below a link to a file with just one mesh. Suppose I want the two cylinders and the cube to each be a different color but to have those colors blend in a nice gradient in the large fillets.

    I've tried vertex maps and polygon selections but cannot find any good solutions.

    Thanks,
    Greg

      Hi Greg,

      Let us start with the blend/blur. I have animated that, so the Timeslider is proportional to the blur amount.
      You can add color to a selection with the Paint tool (Double click on the Vertex Tag while the shift key is held down; open that)

      For the two objects, you might explore this here, and perhaps there is something useful for you in the setup. Both files are in the link.

        @Dr-Sassi Thanks Dr Sassi!

        I am beginning to understand the two files but still have some work to do.

        A follow-on question:

        Is there a way, and I think this is unlikely but 'hope springs eternal :)', to preserve the vertex tags with their colors and fields (from example two) if I were to apply the following to the two objects: Volume Builder, Volume Mesher, and Remesh? Unlikely since the original vertexes of the original two objects do not exist in the output of the Remesh.

        I am looking for some solution so that the blending is procedural. The objects I am working with are complex and intersect in many areas so painting is not the best option.

        Thanks,
        Greg

          Hi Greg,

          Please try this one:

          CV4_2024_drs_24_RSbc_21.c4d

          Tip: The matrix inside the Color Vertex has a point size; explore this for the blend/blur results.

          Enjoy

            @Dr-Sassi I hope you will excuse me, sitting here with my mouth agape in total awe!

            WOW!

            I am flabbergasted :)... I would have never thought of a workflow so clever, interesting, and useful!

            Thanks so much !!

            Greg

              I like the sound of that, Greg.

              Thank you very much for the lovely feedback.

              How to get, produce, and share (re-use) information. That is all I did.

              Enjoy your project.
