problem when rendering using Contours option with inrteractive render

[ittai_frumkin]

When using the Contours option, good results come out , and thank you for that !
The problem is that if you put a rectangular light fixture on the ceiling of the room, even though it is set to Invisible, if you render with Contours option on , in mode Interactive Render you see the rectangular light as black rectangular in the render !
It is possible not to show the ceiling but it limits the rendering options.
It seems to be some kind of bug.

Hey ittai_frumkin,

This might happen because the rectangle light lies on the same surface as the ceiling, what if you move the light a bit lower? Does the same persist?

[ittai_frumkin]

It persists but only with intractive rendering . ( In regular rendering there is no problem )

Hm, is it possible to forward us the project file so we can inspect? You can send it via our contact form along with information about the exact V-Ray/SketchUp versions; make sure to mention this thread in the email as well.

To add an update to this, it is an issue with Lights in general which we're aware of and it requires changes that may take some time to be solved; Thanks to the report our devs will have a discussion about the priority of this bug.
