I just released the version 1.4 of Export to HTML5 plug-in to support the new features of Sweet Home 3D 6.0, even if Sweet Home 3D JS Viewer 6.0 should make this plug-in less useful (actually, it's still useful if you want to reduce the SH3D file to render).

New features in the 3D view are shown in the following scene, mainly:
- polylines and blueprint at ground can be displayed in 3D,
- texts can be written on more than one line with alignment,
- transformations can be applied on 3D models like doors, windows and a new mannequin
- textures can be shifted along their width and height, and X offset on sky texture is used to rotate it around the azimuth.

Of course, all these features are still accessible in JavaScript through the updated API to let you read or change the data you want.
