I was trying to follow this tutorial to create a rope using geometry nodes: https://www.youtube.com/watch?v=2VzYMah-nTg And at 10:14 he does a step where he uses the curve parameter factor as a texture coordinate. When I follow this step, and after plugging my coord attribute into the color I get the following result (shaded flat to make the effect a little clearer) : And here is the result after using it as a texture coordinate on a wave texture: As you can see, there is a segment of the rope where the waves are really squished together.
What I am pretty sure is happening, is that it has a value for each segment in the profile curve, and interpolates between them, and then because the last segment goes from 1 back to 0, because it is a circle, the texture map messes up there. I can sorta fix this problem by increasing the resolution of this circle a bunch, that will just squish this problem area to be really small, but I am planning to have quite a few of these ropes in my scene, so too many vertices is gonna cause problems.
The thing is. It seems to make sense that it does this, considering the steps that are taken in the tutorial, but the strange thing is that I don't see this happening in the tutorial. So, my question... what is Default Cube doing differently? And how could I fix this?
