Multiplies a [Transform3D] and a [Vector3] within the visual shader graph. A multiplication operation on a transform (4×4 matrix) and a vector, with support for different multiplication operators. The multiplication type to be performed. See [enum Operator] for options. Multiplies transform [code]a[/code] by the vector [code]b[/code]. Multiplies vector [code]b[/code] by the transform [code]a[/code]. Multiplies transform [code]a[/code] by the vector [code]b[/code], skipping the last row and column of the transform. Multiplies vector [code]b[/code] by the transform [code]a[/code], skipping the last row and column of the transform. Represents the size of the [enum Operator] enum.
