AC18, CineRender engine, standard objects and materials.
I have a strange situation here: a "Solar Shade Straight" object in front of a window . The louvers are made of perforated steel material (Metal - Perforated Small Dots). If I render from the inside, the louvers are not transparent at all although the light is getting in the room. If I remove the window object everything is rendering normally.
The attached image shows both situations, in the middle there is no window behind the lovers.
