I have troubles making distributed instances rotation follow curve orientation.
This is what I got: (red arrow is showing the unwanted orientation)
This is what I want (red arrow is showing the wanted orientation):
This is my geometry:
In order to align objects along a mesh that you have previously created with
Curve to Mesh, you would need two parameters:
In your case, you would have to capture these before converting the curves into a mesh.
Then you can use these two parameters in combination with the node
Align Euler to Vector to create a rotation that aligns the axes of the instantiated objects to the curve:
