Well, I thought I'd try a whole new approach and found a better way! Houdini is awesome and I didn't need to do what I was doing, instead I just made a tube used the UV-Unwrap node and set it to strip and zero spacing. Normals are of course perfect now and the seams are totally acceptable and it's only two nodes. Only took me 2 days.

I had a play with “fix seams” did some experimenting with and it's even worse for the actual texture as seen in the image. But the normals still stay the same. At the same time I feel I might be taking the wrong approach to procedurally texture this pole with constant pixel density. I was unwrapping it at the seams and computing arc length, which works beautifully except the seams normals.

The normals did not get fixed (back) with Fix Boundary Seams on, and the texture(front) gets squished.

An easy pipe with eight divisions and it's opened to it can be UV'd nicely. In the picture the seam runs from top to bottom and at that seam the normals are not right, they should be averaged and they are not. I tried many things but have not found a solution. The normals sop angle is set to 180 degrees as well. Also tried the facet node and that made no changes either. Any ideas or suggestions?
