I'm doing an "illuminance" analysis. Everything works perfectly fine as long as the plane which defines the position of the "light" component is an xy plane. But whenever I tilt the plane around x or y i get more or less zero illuminance...
1) plane all flat, everthing fine
Does anyone has any ideas of what could be the reason for that? It seems that the luminous distribution as shown in the viewport is not corresponding to the vectors DIVA uses for the simulation.
