The daylight analysis is somehow not appearing for the entire sensor grid but only for part of it.
I modelled my geometry with the surface method. And I set up the sensor grid with the HB Sensor Grid component. Then I used the Point-In-Time Grib-Based method for the daylight analysis. I then connected it to the Spatial Heat Map component.
The image shows the daylight analysis map. I wanted to put more images but apparently new users can only embed one image.
