Using Arrays With ShaderMaterial

[AlexB]

I notice that there's a setTextureArray method, but I don't see any corresponding methods for vec2s, vec3s, etc. 

As an example, if I want something like:

(Typescript)

const offsets: Vector2[] = [
new Vector2(1, 1),
new Vector2(2, 1),
new Vector2(3, 1),
new Vector2(4, 1),
]

And I want to be able to use this in my shader, like this:

(GLSL)

uniform offsets vec2[4];

for (int i = 0; i < 4; i++) {
 vec3 tex = texture2D(sampler, uv * offsets[i]);
// do something awesome here
}

I don't see any easy way to do it. Any clues?

We should definitely add it

do you want to tackle it?

Thank you, this helps a lot!
