The GetVector4 method retrieves a Vector4 value associated with a specified StringToken key from the RenderAttributes collection. If the key does not exist, it returns a default value provided by the caller.

To use the GetVector4 method, you need to have an instance of the RenderAttributes class. Call the method with a StringToken representing the key and a Vector4 that serves as the default value if the key is not found.

Example usage:

RenderAttributes renderAttributes = new RenderAttributes();
StringToken key = new StringToken("myVector4Key");
Vector4 defaultValue = new Vector4(1.0f, 1.0f, 1.0f, 1.0f);
Vector4 result = renderAttributes.GetVector4(ref key, ref defaultValue);
