Ladybug_Sunlight Hours Analysis geometry self-shading?

Hello,

using the component Ladybug_Sunlight Hours Analysis there are two inputs:

- geometry (Geometry for which sunlight hours analysis will be conducted)

- context (Context geometry that could block sunlight to the test geometry)

During some recent tests the results I get are very strange, it looks like the geometry objects are self-shading (i.e. I have a group of buildings surrounding two buildings if I analyse the two buildings separately the result is different than if I analyse the two buildings together). Is it like that? I always thought it was not and that if you wanted to use a "geometry" also as "context" you should have feed that in both inputs. Or something is changed in recent version of LB?

Thank you.

Francesco
