The package contains 11 ships of various types. Some are more elaborately textured/modeled than others as some are made many years ago and others are newly finished. But it is what it is as shown in the promo picture.
Tugboat Smit and ship 'Sea Monster'(multi purpose ship) are the most elaborately modeled ships. These two ships (other than other formats) have 3dsMax/vray version while others are only in These formats: 3dsmax/scanline;C4D;Maya;Fbx;Obj.
The fire boat and an old type tugboat are rather detailed too.
Other ships are mostly mapped only with a diffuse map. If you throw in a general normal/specular map alone with the diffuse, and render with a GI capable renderer with a true hdr file as background, the renders will have a instant quality boost than what you see now.
polygon information of each ship model can be found in their individual product specification section.
There is no HDR files in this package. There might be a call for hdr file upon opening certain file(Sometime I use a hdr as background and forget to remove the link later on). Just ignore it or replace it with a file of your choice.
