HB Imageless Glare Error file not found Error

Hello,

I have been using a glare script for a while now but suddenly it stopped working and gave the following error. Any idea what it could be? I have reinstalled LBT using the latest pollination installer and have no custom radiance materials as well.

Runtime error (PythonException):
The recipe failed to run with the following error(s):

This progress looks :frowning: because there were failed tasks

Thank you for your help!

Hi @SG_siddharthghoghari,

I think this bug has been fixed – check this comment.

Please let me know if the you still have issues after updating the core libraries.

Hi Mikkel,

After using the versioner to update, when loading grasshopper, this happens:

All my Ladybug components are missing. Let me know if you know a fix to this?
