I am trying to simulate an external environment with artificial lighting.
The default fixtures that Ecotect have as LIGHT objects are placed in the
model. When I export this model to radiance, I get the following error:
3020: WARNING: Light object 87 is producing no light - check color and
lumen output.
Indeed, when I look into the RAD file, I see the following:
When I render it this way, there is no artifical lighting. When I convert
the "0.000" values to "255", then I get the desired result. Now, the
problem is, there are so many fixtures in the model that I cannot edit the
RAD file each time before simulation. Why is Ecotect creating the RAD file
with these values? Is there a bug or is there something that I am missing?

You don't want to use the display RGB values here (range 1-255). The
three values define the intensity of the light source in W/m^2. The
right value for your _flood_light depends on the definition of the
distribution and the size of the fitting in the model.

Bug is always possible with Ecotect but I expect that - as the error
suggests - you definition of the light (a type of material in Ecotect)
is wrong.
