Blistered Paint
The surface of this paint is blistering and bubbling due to ageing and bad maintenance.

The SBSAR allows users to adjust the paint color, number, size and intensity of bubbles and dents etc.
 
Black Coffee Foam Texture
It's foam of a black coffee such as americano. A good coffee comes with a layer of crema and this texture has no exception.

There are large and small bubbles scattering around edges. It is the natural phenomenon. Bubbles tend to adhere to surface.
Bubble Wrap Texture for Packaging
It is the most commonly used bubble wrap for packaging goods and products. Each bubble has different degrees of damage and wrinkles.

Opacity map is also provided with the texture because bubble wrap is semi-transparent.

In order to achieve good rendering result, glass shader should also be used.

Metal map can also imitate the excellent result by mixing the opacity and metallic maps for some shaders, so a metallic map is also available, but optional.
