      SketchUp 8 on Windows XP

      I created a cylinder and added a diagonal texture. When I tried to trim an opening with a rectangular solid, I discovered the cylinder was not a solid. So I created another cylinder and made sure it was a solid.

      But now when I add the same texture it is not continuous around the cylinder. The diagonals align between some vertical facets, but don't align with others. I tried various smoothing angles, but had no effect on facets. Shouldn't the surface of a solid object be continuous across edges? The discontinuous facets don't seem to be caused by the trimmed opening.

      Is there a way to make all the facets contiguous and continuous so the texture will be uniform? If I have to start over again, how can I avoid the same problem?

      PS---I haven't been able to get the RpTools cylinder to work.

        First of all, is the cylinder surface smoothed?
        Second, did you apply the texture as a projection?

        Beyond that, someone else will need to help.

        Edit: Actually, honoluludesktop's reply may be the one you want. He squeaked in just ahead of me, but I posted anyway 💚

          Is this a discussion of your problem?

            Normally a texture should auto-wraparound a curved surface but for some reason (that is beyond my imagination and probably depends on local weather rather than any logical things), it sometimes does not. In these cases, you need to

            1. turn on hidden geometry,
            2. right click on one of the faceted pieces,
            3. go to texture > position - do nothing but press Enter.
            4. Now turn hidden geometry off and click on this positioned piece with the Paint bucket tool while holding the Al key (it will turn into an eyedropper too which you can use to sample the positioned texture).
            5. Now release the Alt key and paint the entire surface.
              Sometimes even this does not work and you need to sample the positioned texture from facet to facet all around with hidden geometry on.

              @Gaieus:
              The condition you describe ought to have a famous name and a holiday named after it, since it persists. 😆

                How about the 'Gaieus Effect'?

                  It would be plagiarism as I have read something similar before.
