The folders inside Runtime are mostly hidden inside DS - only the actual Poser library folders in \Runtime\Libraries show - though you can reach them using the vrowse… button for textures or File>Import. As Jimmy says, you would be best off saving the things as a DAZ Studio Sceen Subset, or even as a Figure/Prop asset (File>Save as>Support Asset) as that saves embedding the geometry in each scene you use the item in. Using the native format will also do a better job of preserving material settings than exporting to OBJ or to a Poser file.
Thanks Richard and Jimmy. Then if I get it right, I should not use the export obj option in Bryce when I transfer the files after I have ungrouped the elements of the sketchup initial object? Or is it once I’ve imported the files inside DAZ that using the Figure/Prop asset (File>Save as>Support Asset) that the transformation will occur. Does it mean that I should change manually the place I put the folders? If so where should they go?
Those questions may seem awkward to you but I really I’m a beginner and learn on the spot the basics without any knowledge of the way those things developed as far as programing is concerned. Sometimes when I read some of the tutorials here i have the impression to read chinese!:-) so be so kind as to be very basic in your explanations, the only way for me to get it rignt and retain the method is to get the basics of the operation I should do. Sorry to bother you like that.
