Hi @pedro1 ,
It’s clearly working because the simulation succeeds and the component does not turn red.
An orange component is just a warning and you should look at the full report out of the component to see what EnergyPlus wants you to be aware of since it may not actually matter for your case.
FYI, @TrevorFedyna , the PixelCounting method gets around all of the limitations of concave zones that the PolygonClipping method has, which is what the E+ documentation you posted there is talking about.
So I’m pretty confident that the warning in @pedro1 's screenshot is not related to concave zones. My hypothesis would be that @pedro1 has a Shade in his model with a transmittance schedule assigned to it and the PixelCounting method cannot model transmittance schedules. So EnergyPlus is giving a warning to let him know that the Shade with the transmittance schedules was simulated as totally opaque. Of course, seeing the full report would tell us whether or not this hypothesis is correct.
