[Radiance-general] Radiance on Cygwin: Starting problems

[Kirk Thibault]

On page 21 of RwR, the input file <room.rad> specifies a light  
definition of:

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

# this is the material for my light source

void light bright
0
0
3 100 100 100

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

The structure for the definition is

MODIFIER TYPE ID
0
0
3 R G B

i.e.,  "light" is the type and "bright" is the id.

Make sure you did not accidentally type:

"void bright light"  [that is, switched "bright" and "light" by  
accident] on the first line of the definition.

Hope this helps, been there done that!
