I have a house model, When I try to apply a brick material to it bricks are looking very big , So that I scaled down the material to adjust the size. But Quality of the material is lost. I attached the images of before and after scaling. Before scalling quality is good but size is very big, but after scaling down to correct size the resolution of the material is pixelated. Please some one suggest me to do this in correct way. This is not ony about the bricks, other materials are also behaving like this.
