AngleBetween has a dead spot in (0, 0)

[yar]

Same issues:

AngleBetween won't work if one value is (0/0)

if either input is 0/0 the node just outputs 0 or .5 [skia]

AngleBetween inconsistent behaviour between 2d and 3d versions

AngleBetween 3D version gives NAN when fed with same data as 2D version [image] I think 3D version expects normalised inputs? Confusing because the helppatch shows the 2D version so you don’t expect to need the normalisation when you deploy the 3D one. Also see related
