Here is a SH3D demo file for using the plug-in with new light sources and image-based lighting (sky with texture).

Dear Enko,
may I ask as a Newbie in this Software:
Do really mean that IBL is possible with SW3D.
As far as I know, for IBL usage and renderings, the sky-picture should be a hdri (32bit).
But such hdri´s are not useable in SW3D, right?

So, how is this IBL been done, is it really based on the sky pictures pixels?

By the way:
Many thanks for your phantastic support, here in the forum!
