Sun light reflections showing on wrong sides

[octavio2]

The attached pic show the sun light from a window, which falls on the floor beyond, showing wrongfully on the front of the perforated chairs. 

The perforated chairs are desired in the rendering to help enlarge the interior, which is small, and the sun reflection is also desired to hint of an unseen nearby window with view to the exterior.

In the rendering, the sun shows on front of the chairs, wrongfully, since the sun falls on the floor behind the chairs.

How can the sun reflection be tricked to show thru the perforations behind the chair?

(Note: The tabletop is glass).

Thanks in advance.

I think the issue is in the material of the chair. The Transparancy map for the woven cane material is to blame because the surface it is applied to is infinitesimally thin. Revit is just not that good at this as we would hope. Let's trouble shoot

Does it do the same thing if you render in the cloud?

If you are using 2016, what happens if you switch the engine between MentalRay and RayTracer?

If the above doesn't change anything, I think the only answer is going to be actually modeling that woven material in the family. One tip though, in order to avoid ridiculously long loading times for 3D views, select that new geometry and change the visibility settings to hide it at coarse and medium detail levels. Then you can at lease set up your view before turning it to fine.
