Hi LewisO, as far as I know this is how it works in standalone - standalone also creates one pin which you can plug in a float input node which has XYZ.
If you want separate control pins I would suggest splitting into 3 float controls and combine as a vector afterwards.

Example:

Code: Select all

shader Example
(
    float R = 0.0,
    float G = 0.0,
    float B = 0.0,

    output color result = color(0.0, 0.0, 0.0)
)
{
    vector color_vector = vector(R, G, B);
    result = color(color_vector);
}

or

Code: Select all

shader FloatsToColor
(
    float R = 0 [[string label = "Red value", string help = "Value stored in the red channel of the output color."]],
    float G = 0 [[string label = "Green value", string help = "Value stored in the green channel of the output color."]],
    float B = 0 [[string label = "Blue value", string help = "Value stored in the blue channel of the output color."]],
    output color out = 0)
{
    out = color(R, G, B);
}

But obviously adapt to what you need.
