Re: HQ rendering issue
Since the version 4, you can set some properties of the rendering engine with the SweetHome3D.l4j.ini file (or the Linux launch script) to get some reflection effect as shown as in this thread. I plan to write an article about it but you can already try it yourself with the following lines:

-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.lowQuality.globalIllumination=path
-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.lowQuality.diffusedBounces=3
-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.lowQuality.causticsPhotons=1000000

-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.highQuality.globalIllumination=path
-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.highQuality.diffusedBounces=3
-Dcom.eteks.sweethome3d.j3d.PhotoRenderer.highQuality.causticsPhotons=1000000

See this file for little more explanations about these properties, and expect a much longer rendering process.
