The
Scale
method on Vector classes is intended to scale each component of a vector by the respective component of another vector, and apply the result to the vector whose method was called. This method does not seem to be functioning in Udon. This issue affects all Vector types.
Below is a code snippet demonstrating the issue, along with the expected and actual log outputs.

var v2IntScaleTest = new Vector2Int(1, 2);
v2IntScaleTest.Scale(new Vector2Int(10, 20));
Debug.Log($"Vector2Int(1, 2, 3).Scale(10, 20, 30) = {v2IntScaleTest}");
