Blue Cheese Texture
It is a blue cheese covered with lots of bluish and greenish mould.

Remember to apply subsurface scattering to the cheese material. Otherwise, it will just look like a hard plastic.

The color of the cheese and mould can be changed. The amount of mould and holes can also be changed. The bumps can be amended too. All you need is the SBSAR file.
 
Cheese Texture with Holes
It is a very classic cheese texture that has a lot of holes. The large and small holes are the most remarkable characteristics of a cheese.

This is more like Swiss-style cheese that is always speckled with holes.
