Re: How to create a down light embedded in the ceiling
Maths is confusing for lawyers, evidence depending on two events, each 70% likely, sounds pretty probable to most. Which is wrong. Never give a lawyer two variables.

Last attempt of the day, a directional downlight with
<light catalogId='okh#spot_dir_cut' name='Spot_focus_dir' creator='okh' model='1/downlight_directional.obj' icon='0' x='69.5' y='290.55923' width='20.0' depth='10.0' height='10.0' modelSize='14936' staircaseCutOutShape='m .52,0.5 a .23,.46 0,0,1 .46,0 a .23,.46 0,0,1 -.46,0 z' power='0.4'>
<lightSource x='0.25' y='0.5' z='0.7' color='00BB9854' diameter='0.125'/>
</light>
Point is, concept works, but the two variables are hard to handle. For me, anyway. LightSource diameter, LightSource placement in model. Which is the better generic model?

All models in spot_light_cutout_dir.sh3d should be placed 0,5 cm below the ceiling for the cutout to work.
The Spot_focus_dir model can be adjusted in height to raise/lower the beam.

But is any of this useful? Not sure. Could it be with the right settings. Probably...
