Ecotect, DIVA and Radiance

HI All,

I have installed the DIVA for Rhino plugin and since there I can no longer
run radiance grid analysis directly from Ecotect. I am getting the following
error message in the dos window:

"rtrace: fatal - command line error at '-sj'

Which then results in no data being written to the grid file.

In addition I cannot recall how to reinstall everything to its original
state as it was operating before installing DIVA for Rhino.

Any help with this would be appreciated.

Regards,

Bayanda

Hi Bayanda,

I don't know if this is of any help (I never worked with DIVA), but your problems reminds me to the release note of Radiance 4.1 which says that the -sj option has been changed to -ss:

****** COMPATIBILITY CHANGE ********
Changed -sj (specular jitter) option to something called specular
sampling (-ss), which if set less than 1 has the same behavior as
the old -sj, but when set greater than 1, spawns multiple ray
samples from semi-specular surfaces.
For details see: http://radsite.lbl.gov/radiance/refer/Notes/ReleaseNotes.html#Version%204.1

My best,

Iebele

It looks like the version of Radiance shipped with DIVA is incompatible with the one required by Ecotect. Since the version shipped with DIVA is the more current, I am not sure what to do. Do you have an Autodesk support contract for Ecotect?
