I've just started using this package - it's really fantastic. I have some questions about lights that I've been unable to find an answer to in the user documentation or forum.

1. What is the impact of change the size or angle of a light? I'm playing with just basic white and incandescent lights, and changing these values doesn't seem to have any impact. I've tried with both ceiling turned on and off, and I get light/shadows, but changing the values seem to have little impact.

2. Using the Advanced Renderer (Tools-> Create Advanced Photo), when I render the image, most of the furniture pieces disappear. If I use the standard photo renderer, all of the furniture is visible.

3. How do I import the the light plugins (basicLights.sh3f, BasicPlusExtraLights.sh3f)? I'm running on Linux, and I've copied them into ~/.eteks/sweethome3d/plugins and restarted the application, but I don't see these features.


Thank you
