Any recomendation regarding 3DS exporting options from Sketchup (other than those from picture) of large complex roof structure that will be use in a calculation . Luminaires will be aimed at the roof as indirect lighting. I'm asking because we are questioning results obtained in AGI32 and Dialux have huge discrepancies (Dialux results are half from AGI). Dialux calculate way quicker (using the standard method). Using same reflections.

-Is there options that coud be switched on to improve acuracy? I'm questioning rebound quantity in calculation method from each app ?

-Should I use .sat format instead?

Thank's
