Yesterday, Senior Product Manager, Tatjana Dzambazova, let me know that the http://memento.autodesk.com/projects/popular - Memento Gallery with online viewing/sharing and a new memento build with 'Publish to Gallery’ are now live on the http://memento.autodesk.com/try-memento - site . Here are some tips about publishing to Gallery:

• Download and install build 1.4.0.1 from the website — you will notice a button "Publish to Gallery."
• With this new build, you will be able to set the thumbnail of your published model (orient and zoom the model as you wish your thumbnail to look like in the UI and click on the capture camera button in the publish dialog).
• You will also need to define a name of your model, can add tags and description, and decide if you want to share the ORIGINAL RCM files with others (to make it downloadable).
• Once published, the model shows a PNG preview and 3D model. You can change the background and lighting of the model as desired.
• To add additional images, videos, or manage your published models, sign in on the Memento Gallery (sign in link is on the top right). You can add photos of your 3d prints, wireframe PNGs, etc. For adding videos, they will need to be first published on YouTube, and you provide the long YouTube hyperlink (the browser link, not the short YouTube hyperlink), and you must click DONE button at the bottom of the screen after inserting the URL.
• We added ability to share the 3d models with HYPERLINK or to embed them in HTML on websites (top right in the viewer itself).
• From within the Gallery, you can also publish your own models to Sketchfab.

As models will be decimated and even have their textures rebaked to fit within the file size limit (250 MB) automatically, large models can take some time to publish. Be aware of this for time needed. As a workaround, you can try decimating (and re-baking by exporting your model to the OBJ format), before publishing to the gallery. The gallery's viewer is consistent to the main motto of Memento which is to simplify all processes, so users won't need to manage the number of polygons that a model has for WebGL support or the baking of textures to make models small but look good when published on WebGL. In this regard, the moment you click Publish to Gallery in Memento, Memento does it all for you in the background!

Gallery souvenirs are alive in the lab.
