Adding Items to the Library Palette (Manual Method)
You can also add items to the Library palette by creating folders and subfolders in the Poser hierarchy and adding your items directly to those folders. Please refer to Poser File Structure for more information about the Poser file structure.
This is an advanced feature that should only be undertaken by advanced Poser users who are familiar with creating custom content. Manually adding Library items could result in misplacing files, which could cause these Library items to be invisible and/or unusable. Bondware, Inc. cannot provide technical support for people who manually create content folders. If you purchased content and are unable to get it to appear in the Library or if it has other errors, please contact the content creator.
The library thumbnail size has been increased from 91 x 91 to 300 x 300 in Poser 14. Thumbnails will also be created if you save scenes outside of the Poser library. The Poser Launcher also uses 300 x 300 thumbnails for scene previews.
