(Using Blender 3.3)
Since particles seem to be deprecated, I am trying to use hair curves to allow me to precisely position instances on a model. (Consider feathers, as an example.) Specifically, want to position an instance at the root of each hair, using the hair's orientation and size.
This works fine for position and orientation, but I can't figure out how to correctly map from the length of individual hairs to per-instance scale.
I'm testing with a single hair, 0.1m long. Both Spline Length and Spline Parameter are giving different results compared to plugging in 0.1 as a constant scale. (As far as I can tell, both are in fact producing 0.) Curve Length seems to give the correct result, but of course that's only useful if I have exactly one hair.
How can I get the length of individual hairs in a way that I can plug into instance scaling?
