vray mosaic material

hi all

i have downloaded this mosaic material :

http://www.vray-materials.de/all_materials.php?mat=549

 

but it does'nt seem to render correctly.. here is my problem:

 

when i try to create project on my own (unit size in max is set to one centimeter) and for example i create floor of dimension 400x400 cm and when i apply vray material it is just too big. So big that it is not useful at all. For example grass is not looking like a texture or something. It looks like one color of green and that's all. That same grass which looked good when i do web tutorials now is looking like it is zoomed too much in.

 

I tried to fine tune it. As far as i understand it it does have something with map tiling. So sometimes i increase or decrease values in Map coordinated but mostly it is hit and miss.

 

Add to that that some materials have bump and displacement map and i am lost.

 

So my question is why does some materials looks fine on some of my objects but when i create my own project they are shockingly big or very very tiny and small?
