texture a curve

Question

I have a curve (and i don't wanna convert it to mesh) and i want to texture that curve:

Unfortunately my texture is getting stretched on the straight parts.

How can i have the same distance of the rings on the circle part and on the straight part?

shader nodes:

resampling curve via geo nodes seems to be the only solution :( or you can subdivide the straight parts to get a uniform vertex density (ok solution for simple curves) — Shantanu Aryan, Jul 14 '22 at 13:57
It doesn't seem possible: https://blender.stackexchange.com/questions/1670/how-to-texture-a-beveled-curve-without-stretching ... maybe you can try to subdivide the straight part — moonboots, Jul 14 '22 at 13:59
wow, that's so sad :( is there maybe an add-on which resamples a curve geonode can do? so that the distances between control points are equal? or wouldn't that help at all? — Chris, Jul 14 '22 at 14:01

there is no "use uv for mapping" checkbox anymore...and i don't get it working. If you can...i would appreciate it if you show me how — Chris, Jul 14 '22 at 14:28
...it is still possible to achieve the desired result. Guess what? With Geometry Nodes, hell yeah! https://blender.stackexchange.com/questions/43146 — quellenform, Jul 14 '22 at 14:37
@Chris Is this the look you are after? a curve with this texture https://imgur.com/a/cWTTjVj — Emir, Jul 14 '22 at 15:20

ok, this works for me now:

so i give the factor value to the group output and use that as uv value.

+1, the easiest way. In one direction. The other direction will not work like this, but for this purpose it is enough. – quellenform Jul 14 '22 at 14:40
I still try to understand your solution – Chris Jul 14 '22 at 14:43
