thank you. when you are loading an object in DS then you load the CR2?
The other way round, if it’s a figure. For example Hiro 3.cr2 will load blHiro.obj from the geometries folder. The obj is the base mesh; the cr2 contains deltas for the morphs, materials data and other figure set up information.
Obj files are a standard format used by many applications, often as an exchange format for importing and exporting, as well as being internally used for mesh data. They can be saved with a companion material file (.mtl) which holds materials and texture data, but for morphs and base shapes only the obj is required as that contains the vertex information.
When you import an obj into DAZ nothing else loads, unless there is a .mtl file with it. Although DAZ can load cr2 files, of course, it has it’s own formats and doesn’t need them per se. They do have cross platform support with Poser, which has been traditionally essential, so you will see a lot of Poser format files in your DAZ runtime (in fact the “runtime” is a Poser convention in itself).
