Quote - First version with GUI parameters. Not mutch parameters are included yet. Have to explore which format Lux needs for the parameters.

If that helps, there is a big package with Lux test scenes in their mercurial, that's where I found the syntax for tweaking the exporter files.

Quote - Another findout: I wondered why some spot-light where ignored. Seems that "Angle End" for a light in Poser has to be changed to a higher value than 70 (default). I raised it to 160 and my light was working.

So you're saying you can't make any narrow spotlights? Now that's a limitation...
(BTW the lights which didn't work for me were infinite ones)
