algorithmic modeling for Rhino

"rtrace: warning - No light source found" message

Hi Guys,

I get the message below when running a daylight illuminance analysis.

This is strange as I have selected the Boston weather file and ran an analysis that worked well on Rhino. Just checking if this is a problem, the simulation is still running quite well despite the message. Do I need to add a light source too?

Many thanks,

Arthur

Hi! I got exactly the same problem. What was the solution? (Apparently there is a missing comment on this page..)

Thanks
