Spline radius become incorrect

I have a bunch of splines (specifically 8 in that case).
All splines have variations on their radius.
I sample they radius and create a new spline on their ends.

Here’s how i sample the splines radius:

Im expecting what all my newly created splines “tips” will have the same radius and its kind of works, but not really.
Here’s how the “tip” forspline with index 0 look like:


As we can see the radius are perfectly match with the “parent”.

But here’s the spline with index 5:


Radius for the “tip” are already incorrect.

And here’s the spline with index 7:


Radius for the “tip” are becoming even more bigger and even more incorrect.

I double check the whole graph to be sure what im passing correct data and didnt have anything which may introduce some unwanted randomization, etc.

Maybe im just sampling the splines in a wrong way?

Could you share a blend file?

Well… looking at the bit of the network you provided and your description there is so much wrong with your approach I’m surprised anything works at all! :sweat_smile:

Something like this would make more sense for a multi-curve setup:

This is another approach to extending the end-points of curves:

Good luck.

C’mon its not that wrong :sweat_smile:
I was just need to realize instances (i need to do it anyway) and properly sample input splines. Converting to points can eliminate the needs of align euler nodes:

Even if you’re scared of the align node, your setup is still too convoluted (and you still don’t need the Sample Curve Node):

Good luck!
