This function is not supported in earlier versions. |
Sends one or more colors to a special (extern / uniform) vec3 or vec4 variable inside the shader. The color components must be in the range of [0, 1]. The colors are gamma-corrected if global gamma-correction is enabled.
Extern variables must be marked using the extern keyword, e.g.
extern vec4 Color;
The corresponding sendColor call would be
shader:sendColor("Color", {r, g, b, a})
Extern variables can be accessed in both the Vertex and Pixel stages of a shader, as long as the variable is declared in each.
In versions prior to 11.0, color component values were within the range of 0 to 255 instead of 0 to 1.
