Electric_lighting_view sample running error

1

Hi,
Just updated to the latest version with the Pollination installer [1.66.11.0]. Noticed there is a new option for electric lighting simulations.
Great news and thanks for this new feature!!!

Started trying the sample 'electric_lighting_view". Unfortunately it gives the following error:

  1. Solution exception:
    The recipe failed to run with the following error(s):

2026-01-23 10:01:25 ERROR: “CreateRadFolder” failed. See below for more information:

This progress looks :frowning: because there were failed tasks

I assume @mikkel is the address for this one. Hope you can help.
Thanks,

You can try to sync the grasshopper file

Hi @AbrahamYezioro,

I just pushed a fix, so give it 30 minutes to an hour and you should be able to get the fix with LB Versioner. There was a bug that set the identifier to the whole file contents if the Luminaire was created from the string contents (as in the sample) rather than the IES file.

In the meantime you can run the sample by giving the Luminaire a _name_, or alternatively you can run the sample by using an IES file, which I would always recommend. The sample uses a string in a panel, which makes it easier to share a sample file that you can run straight out of the box.
