Where is the longitude argument in the cloud-object ?

Anonymous — Thu, 11 May 2023 12:23:09 GMT

I've bought the book "Lightworks in Archicad" and I've come to page 43. Here are some parameters like longitude and latitude and shadow quality mentioned. I use AC 12. I think this book has AC 9 in mind. I can not find any arguments like those I mentioned in the cloud-object.
What has happened to them or am I at the wrong place?

Hi Anne,

Things have changed since Dwight originally wrote the LW book. Be sure that you download his free supplement for AC 11 to read about some other changes.

The Sky object has a parameter as shown in the attached screenshot. Changing to 'Quick Method' as shown gives you the parameters mentioned in Dwight's book.

Note that with the new 'realistic sun' option in the LW rendering settings dialog, you are likely to not need the sun object at all (other than Dwight's "under sun" usage - to illuminate the lower surfaces of objects, such as roof soffits, which might otherwise appear much too dark since LightWorks in ArchiCAD does not implement radiosity or global illumination).

Cheers,
Karl

Hi Karl

Thanks for your information, but where do I find the free supplement for the book?
