The final version of Sweet Home 3D 7.2 is out with a few more corrections in 3D handling.

Thanks to all for your feedback and your tests [:)]

As Keet noted here, I was able to add a new property to my library lights to replace the use of the Description property which can be changed by the user.

By using the system property [font=courier new]com.eteks.sweethome3d.additionalFurnitureProperties[/font] in a configuration file for the installer or as a JAR executable parameter, it is possible to display the new property column without it being editable because in this case the Other properties button does not appear.

As for the management of this new property by the rendering plug-in, simply retrieve the object property from its name and test the values.
