I want to create tubes using geometry nodes. I want to use different materials for the caps and the sides. I reduced it to a solid strand while i solve my rotation issue.

The problem is that I can't figure out how to rotate the end caps.

Here is an attempt using "sample curve" for the cap positions. I have also tried "instance on points" with "select endpoints" with a similar result.

    $\begingroup$ If you Instances on Points and use an Align Euler to Vector with a Curve Tangent connected into the vector socket it should work (Z axis). $\endgroup$

  • $\begingroup$ Works! Alignment axis: Z, Pivot: Auto, Factor: 1.0. @Vagabonk You want to make it an answer? $\endgroup$

  • $\begingroup$ Hi, John! Glad you've got a fix! .. (BTW, don't forget to flip one end.) This question might be clobbered, though, as a duplicate of blender.stackexchange.com/q/243389/35559 .. would that be fair? $\endgroup$

  • $\begingroup$ @RobinBetts I looked at that before posting. Thought it was different with the spherical ends. $\endgroup$
