Spatial heat map shows same value while it suppose to be different

Hello, I really need some help.
I’m doing point in time illuminance analysis using HB PIT component. This is the n-th run, so I’ve run the same script previously with no errors, but suddenly the spatial heatmap didn’t show any difference in value and colors. I’ve tried to adjust the legend parameters and do overall trial and errors to find the issues but nothing seems to be wrong. The only thing I changed in this run is the input for sky type.


It’s all blue like this with only a single value, previous analysis with same models and same radiance settings shows range of values, then issue comes and it only shows 0 value, I redid the script in a new file and the newest result is like the screenshot I sent above.

I attach my file here,
VDI test.3dm (183.6 KB)
VDI.gh (100.4 KB)

Any input will be very helpful, I’m really stuck and cant seem to find the solution

What direction did you use for your sensor grids? Did you use the normals of the mesh faces coming out of the “LB Generate Point Grid” component?
