Honeybee plus contour plot doesn't show solar patches

Hi everyone,

I’m doing a study that involves running a 5 phase daylight simulation using honeybee plus.
The geometry is a simple rectangle with a south window and a perforated shading screen. The window and screen have been generated together using WINDOW 7.8. The simulation runs fine but the contour plot doesn’t show the solar patches that would have been produced due to sunlight coming through the perforated screen. I tweaked the analysis grid size along with the perforation size but it didn’t change anything.
Is this a nature of HB+ to not have solar patch details? Or am I missing something?
