Can I simulate a building's own shadow cast on itself?

[ctrhino]

I am trying to simulate the shade generated by an array of simple rectangular units. There are a few windows on each unit which I am using to calculate the mean daylight autonomy for all the units. In this case the “context” used for shading is part of the simulation and I want to know if I can use the same unmodified list of unit volumes for the room component.

Thanks.

Hi.

If running a radiance based daylight simulation, anything defined as context will block rays.

Remember to use HB Color Face Attribute to check that your model as seen by radiance is sound.
