I am trying to get the SeattleSpaceNeedle.ac light on when dark.
I made use of suggestions contained in model-howto.html
Now I have a .xml file with the following content, but that does not
work correctly.
I want a part of the SpaceNeedle to emit red light at night, and then
emit no light in the morning.
I've set two animations with one condition each; the conditions compare
the current sun-angle-rad with a fixed value; one condition should make
the Needle light on, the second condition should bring the Needle back
to no emission.
Result is the Needle lights on correctly when sun-angle-rad is greater
then 1.57 but it remains that emissive even when sun-angle-rad is back
smaller then 1.57.
Am I doing something wrong?
