How to make tile image smaller on scene?

I have 2 tile image 256x256 px size and 32x32px size, but when I put the object on scene the size is the same and I cant make it smaller.
Please help…

Edit your mosaic objects and give the good size to the mosaic :
Default size is 32x32, but you have to manually specify the size of your mosaic texture : the software doesn’t detect it automaticiallly with mosaic objects.

Thanks Kink, now I can have tile image with different size on scene.
