Re: Architectural shader and inverted faces.

There is a default for the shader under " additional options"  > turn off weak internal reflections.
if you turn it off it should behave correctly.

Hi,

it seems the Architectural shader does not behave properly on geometries with inverted faces. I have a simple grid with half faces inverted, and although the "Visible Geometry Side" parameter is set to both in the mental ray optimization tab, the reflections are different on each half of the grid, as if only front facing polygons were taken into account.
it seems to be only happening in the reflection computation, the diffuse part seems to be using the properly inverted normals.

Does anyone know a workaround for this?
