This is a model of a strip of bacon that cooks until it is burnt.
In the native 3dsmax file format, the scene uses 4 morph targets (raw,lightlytoasted, toasted, burnt) with 4 textures to get the effect. An animated displacement map also runs through the mesh to make it ripple.
All morph targets are also separate in the file.
In all other formats the meshes will be static.
