Correct direction vector is when vector.X + vector.Y = 1.0 !!!
For example:
vector.X = 0.3
vector.Y = 0.7
But in UE4 is not like this. It’s about vector.X + vector.Y > 1.0 (~1.5)
Not sure what the purpose of this thread is… need more information.
Pretty sure that a normalized direction vector is supposed to have its length at 1.0, not the sum of its components.
For a 2D vector, that would be the square root of x² + y² = 1.0
