Marc, >>On a cylindrical or spherical surface you also can't use Repeat, instead you again create the tiled map but roll it, split the object into two subgroups and map separately onto each subgroup rotating appropriatly. << The Repeat setting does not work on Cylindrical (Flat X, Wrap Z) and Spherical (Wrap X, Wrap Z) mapping AT ALL, so forget about that. You don't have to do any tiling before you apply a map of this type. You just need to make another SEPARATE image map, with the seam `rolled' into the center of the image. >>This way you hide the `Altitude' seams of both images in a part of the object where they aren't visible.<< This was probably a poor way to put it. If you apply a Spherical or Cylindrical map exclusively to a Subgroup, only part of the image will show up on the rendered object. So the idea is to make sure the part that shows up on the Subgroup does not contain the `Altitude' seam. You do this by rotating the second map 180 degrees as I described. >>If I rotate around and look from the side will I see them?<< By using two images with seams in different places, applied to two opposite Subgroups, you can prevent either `Altitude' seam from being visible anywhere on the object. Tim P.S. Please remember that these remarks relate to the unique seam created ONLY by Altitude maps.
