Surface mapping (below) seems to work best for this wood texture on a sphere: [Screenshot 2026-07-27 113743] but a displacement map (below) condenses certain axes, wrinkling the poles: [Screenshot 2026-07-27 113758] Planar UV mapping (below) doesn’t work as well for the colour mapping: [Scre…

looks like you just need more polygons in your displacement.

Thanks Kyle. I’m not sure where that’s set. However if I use smooth (which may have the same effect) on the current extracted render mesh with settings strong enough to get rid of those wrinkles it smears the texture like so: [Screenshot 2026-07-27 131154]

Sometimes when I weld it after smoothing, I get the seam running down to the front right in the image below: [Screenshot 2026-07-27 132501]

Actually it turns out that reducing the number of polygons with the mesh command can be tuned to smooth the poles without smearing the colour mapping, but it leaves a few jagged holes in the mesh closer to the equator: [Screenshot 2026-07-28 095733]

I guess the question is, do you need displacement, (actual movement of the surface) or can you get away with bump mapping? (a render trick) what is the goal of this project and what is the final deliverable?

True. Turning a sphere from wood will result in a rather smooth, possibly even very smooth finish, once waxed, oiled, or otherwise treated for longevity - so there is no perceptible relief around the perimeter, unless one sits somewhere inside the wood grain ; ) [61M5l9RTnCL._AC_UF894,1000_QL80_]

Thanks Kyle and Lagom. This is a test for creating drawings of an object to initially to be presented and then for construction. With both elevation and section edges following the irregularities of the texture more or less to scale. I have done this in some cases already, semi-succesfully (I onl…

gotcha… ok… there are 2 ways to do displacement in Rhino. one, using the displacement modifier that accepts a texture and then creates the displacement. All the controls are then controlled directly in the displacement panel. This is a an example of that. note this is simply the displacement… no…

Thanks Kyle. I follow. Viewing Brian’s video several times over the past couple of days got me to where I am as of a few hours ago. I’ve been deploying the strategies you just posted. I’ve made a fair amount of progress to where I’m finessing the Detailed Mesh settings with the “Mesh” command to ex…

the wrinkling at the poles may simply be a uv mapping issue.. . see this video from brian [New in Rhino 8 - texture mapping and UV mapping]
