}

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // Shader vectors are always Vector4s.
        // But the value here is converted to a Vector3.
        Vector3 value = Vector3.one;
        Renderer renderer = GetComponent<Renderer>();
        renderer.material.SetVector("_SomeVariable", value);
