THank you very much , your help is above my expectation 
seriously . I came to another question … i need one square to have fixed size for example 100 unreal units . How to tell to spread as many as posible over one plane? becouse this is texture so it will first spread as one sampe an then you can divide it as many times as you want this way but at the same time i dont have control over size of it.
With texture object node i could attach number node to ‘size’ and have it fixed. it multiplied but you know what the problem was .
