Emission light does not show with physical camera, why?

[Charlie2]

Hi,

I have the following problem.

I have a room with some lights in it. The windows have a view to the exterior mapped onto them. Outside I have set a sunlight, which renders fine through the windows when I use the pysical camera.

The only problem is, that I have some lightbulbs, which should reflect in a glass table. I used an emisive material for them. When using the physical camera together with light cache the scene is nicely lit up, but the light bulbs do not show up (=they stay black).

When I turn the physical camera off and use the standart cam I get an extremly bright picture and if I use the same settings with a basic object in an otherwise empty Rhino file the emissive light shows up.

So I presume that the physical camera and the emissive material do not work well together. According to the manual I should use the physical camera though when I use sunlight.

Any thought how to combine sunlight (through the windows) physical camera (which I like as I like real and meaningful settings!) and the emissive light on the lightbulbs?

Maybe someone can suggest which render engine/settings work best or even upload a settings file?

Would be cool!

Thanks,

Charlie2

Have you tried cranking the emissives intensity way way up? Like to 10,000?

Yeah - either that or modify the exposure settings of the physical camera so it is more sensitive. Or just use the standard camera.
