In reverse order, I use whatever scale is comfortable in Carrara, import to Poser using the "send to center" and "percent figure size" options, and deal with re-scaling there. I've done the same with morphs -- Carrara is uncomfortable to work in at Poser scale; the selection handles get offset from the actual selection points, for instance, and the surface display is bad. I've found I get "close enough for jazz" results by scaling up in Carrara until it is a comfortable working size, using the "percent figure size" option when re-importing to Poser, and, in Poser, going to wireframe view and isometric camera and nudging until my morph is exactly on top of the original, un-morphed mesh. I suspect my way causes a little "morph shiver" during animations, but I find it plenty good for stills -- and a lot faster to do than my description might imply. Now, both seperate objects in a scene, and named polymeshes in a single vertex object, will show up as "groups" in Poser. If you assign different textures to your objects, they will also generate Materials in Poser. One thing that may give you screwy results is Carrara will insert extra "g" statements for any Carrara group and for the Carrara universe as well. However. Getting materials in and out in one piece, within a single mesh, I've found astoundingly difficult. Part of the problem may be that even if a Carrara vertex object has different material zones, Carrara won't actually export an obj with materials -- unless you've gone and created specific textures for each of those material entries. For that reason, and for ease in UVmapping and grouping, I've gone to a pattern of creating named polygons for all materials and groups, fixing the mapping and checking the mesh in Poser, then renaming selected groups as materials (aka "usemtl" statements) with a text editor. Carrara of course tosses the materials names anyhow, giving you for instance, for a material that contains both glass and metal parts; "Glass_0, Glass_1, Glass_2." A little renaming makes it easier to work with in Poser. Basically, I've found applying a little text editor on the obj file exported from Carrara solves a lot of issues with grouping and materials. When I have a chance to open both programs I'll see if I can screen-shoot the settings I've been using. I think for most things (modelling something new in Carrara, rigging it in Poser) I just use the defaults on both.
