Hi Tracers!

For the illumination of spaceship corridors, I want to arrange some
visible area lights.
But every time I try to use area_light in combination with looks_like,
the object in look_like is strangely cut...

See you in Khyberspace!

Uh, hey, your light is below the sphere and global ambient makes the sphere
black if unlit.  So... ta da! that's why.

Yes, meanwhile I found it out on my own... obviously the object coordinates in
a looks_like object are RELATIVE to the light_source position!

And then there is the problem of light_sources (with looks_like) within a
CSG... I noticed that in this case, the light_source is pretty well visible,
but the surroundings are not illuminated at all!

Perhaps I find a solution during the next hours... watch out! ;-)

See you in Khyberspace!
