area light

Hi!
I tried to make an area light (created an area light in C4D), but it wasn't imported in the xml-file. Is there a trick? I gave the light in C4D a indigo-light-tag. But it didn't work. Is there a special trick or bug?

You have to use meshlights.

Take a plane, make it editable and use this as lightsource.(as you will
see the normal direction is important

)
No other possibility yet (afaik).

This means, the plane needs the indigo-light-tag? The position and direction is then taken from the plane?

OK, thanks! Seems to work. Can i switch off the sunlight? That only the meshlight illuminates the scene?
Not sure about that....

To remove the sunlight simply remove the sun-nullobject in the
rendersetting-tag. To remove the background light i think you have to
remove the <background>....</background> element in the xml by hand.

Hmmm, when i remove the null-object (as default, this field is empty) and i start indigo, theres an error about the lack of "radiance".
For the background, i set the color to 0,2,0 (near black)....
