I will try a basic explaination here using P4 dude as the example. P4 guy uses 4 files to operate in poser4 on a PC .obj file, this is the mesh itself and also has the texturing info. .rsr partnered with the .obj, this is a short-hand version of the .obj file that poser uses to load the figure faster. From time to time this file may become corrupted and need to be deleted, after which poser will take a few extra seconds the next time the figure is loaded to rebuild it. .cr2 file, this file is poser specific and contains the info to make the figure move and morph. .rsr file partnered with .cr2, again a shorthand version of the .cr2, this also contains the thumbnail that shows in the library. I don't think poser will rebuild this file if deleted, but it really isn't a required file (you just won't have a thumbnail) UVmapper will not change the shape of a mesh, but what it can do is useful in that it can map out and .obj file giving you a template so you can create your own textures, and for more advanced users it can also reassign parts of a mesh to different groups and materials. If you want to turn P4 guy into popeye you will need to morph him, you do that right inside poser using the parameter dials. In case the standard morphs don't do what you want them to and you need a custom morph you have a few options. 1. find a site that has a morph and import it into poser 2. create a morph with magnets (a poser4 feature) 3. create a morph with a 3d application (anim8or is a good free one) and import into poser as to the texturing portion of poser Textures are simply pictures that are strecthed over a mesh, like a nylon stocking will strech over a leg. the texture will not change the shape of the mesh, but the mesh will change the look of a texture. You can find many free textures for your figure here at renderosity in free stuff.
