Error Custom HB Glass and Window material

I’m getting intermittent fatal errors running the HB UTCI component when i try to use custom material properties for the window material, Glass material or Shade material. Sometimes it will run after one or two tries at running the simulation, or adjusting material properties back and forth but other times i get this error:

  1. Solution exception:The recipe failed to run with the following summary:

This progress looks :frowning: because there were failed tasks

Admittedly i could be misusing the components? I’m trying to model a shade as the roof of a HB room, with windows for walls. Since the windows still have high surface temps even after using the HB Window component (see I’m trying to set the windows material properties so that they are as ‘invisible’ as possible in the energy modelling. But i dont understand why it would work sometimes and other times not. (216.6 KB)

I’ve attached the gh file for a better understanding. The problem components are highlighted in red.
