Material vector: Difference between revisions

Revision as of 13:24, 27 June 2019

A material vector is a collection of values used with some material commands. They most often represent a RGB color.

$scale "[1 1]"
$color "[1 1 1]"
$color "{255 255 255}"
$envmaptint "{100 0 58}"
$vec4 "[1 2 3 4]"

Quotes are always required, because there are spaces in the value.
Values inside [square brackets] are used as-is, often for floats or normals. They are normals for colors.
Values inside {curly brackets} are divided by 255, so that standard RGB integer 0-255 values can be used.
Between two to four values can be used, depending on the requirements of the parameter. Listed below:

A vector with two values.

A vector with three values.

A vector with four values.

Access an individual component of a material vector like this:

$my_vector[0]
$my_vector[1]
// etc.
