DC Image based recipe- no valid images

I am using the DC Image based daylight recipe. The simulation runs without any errors. However there are no valid HDR images that are getting produced. The HDR images are 1KB, and the gif images are 0 KB. The Glare analysis component says 1. Solution exception:need more than 1 values to unpack. and the LB image viewer says that the image is not a valid object.

While running radiance, the command prompt showed the following 2 errors.

  1. gendaymtx warning unusually bright at 6.5.
    2.radiance fatal command line error at ss

It looks like something went wrong in the simulation. Maybe @sarith or @mostapha have an idea since they did the implementation of this in HB[+]
