How to get a “What’s New?” newsfeed from Google 3D Warehouse:
1. Type in the name of your favourite model-maker, or keywords for the type of props you want.
2. Then select the drop-down, to re-order the results by date. The most recent will appear first.
3. An RSS feed button for that search appears on the far right of the results. Click on it.
You’ll also find RSS newsfeed buttons on themed collections of models.
