A material vector is a collection of values used with some material commands. They most often represent a RGB color.
Syntax
$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 normals . For colours this normally ranges from 0-1. - Values inside
{curly brackets}are divided by 255, so that standard RGB 0-255 values can be used. - Between two to four values can be used, depending on the requirements of the parameter. Listed below:
vector2
- A vector with two values.
vector3
- A vector with three values.
vector4
- A vector with four values.
Accessing
Access an individual component of a material vector like this:
$my_vector[0] $my_vector[1] // etc.
