Honeybee materialLib Exception

Leaving this narrative of fixes up here in case someone searches for the keywords, otherwise I fixed what I broke. The definition setup itself works.

----

Edit 2: Solved. Old version of gencumulativesky.exe did not accept -p parameter and made empty sky.cal file.

----

Edit: solved run problem, Bee did not download OpenStudioMasterTemplate.idf

Get it here: https://github.com/mostaphaRoudsari/Honeybee/issues/119

Now get empty HDR:

Hi friends,

trying to get a cumulative sky image metric to run and encountered an issue with the image-based metrics component. It throws:

Runtime error (KeyNotFoundException): honeybee_materialLib
Traceback:
  line 768, in main, "<string>"
  line 1442, in script

I guess this is some sort of setup issue on my end, or I messed up the definition? Any help appreciated.

Thanks,

Max
