Here's the first version of a new plug-in able to render images depending on sun's position.
This plug-in is available at http://www.sweethome3d.eu/plugins/Advan ... g-1.1.sh3p

This new item displays a dialog box with new options (English and French are supported):



The lights you can turn on or turn off are the ones included in SH3F libraries, but some of them don't have any effect.

Source code is included in the plug-in.

Have fun [:)]
