[Radiance-general] Confused by GenSky

[Paul Lovell]

Hi Christopher,

Yes, that gets tagged-on by another part of the wrapper (spaghetti code). My actual world.rad file contains this:-

*******************

# C:\Program Files (x86)\MinGW-Radiance\bin\gensky -ang 45 45 -s

# Ground ambient level: 14.8



void brightfunc skyfunc

2 skybr skybright.cal

********************



Other bits of the scene are represented in another file <the rectangular groundplane and horse).


You did direct me to one bug, my specified sky colour was ignored and [1 1 1] was always inserted. Luckily I've only ever used a [1 1 1] sky, thanks for fixing my future-bug.


George

Do you have a sky dome hemisphere definition in your scene such as the following? It would have to come after your gensky command in the scene.

However, when I try with the -s sky:

It just fails to render "pfilt: picture too dark or too bright ". The -c -u -i skies also don't render.
