Cannot reduce background illumination

Hi,

Since this afternoon, I cannot reduce the background illumination anymore.

Is there any parameter I don't remember?

I believe that in order to use the Lighting Channels dialog to change the illumination of the background image, it would have to be a light source. You can make it one by using the Create Planar HDRi Image button on the Options/Background tab to convert the image to an HDRi image. After doing that, you can change it's illuminance in the rendering using the Sky setting on the Lighting Channels dialog.

Otherwise, you can change the Brightness of the background image using the Background Image Filters - Brightness control on the Image Layer Wizard. That might do what you want to do.

In fact it works back, don't know why!

We don't need a planar hdri, a simple jpeg also works as shown below:

Sky = 0.03

sky=0.06

sky=0.09

but maybe and hdri sky could give a better result because like that, model illumination is qickly too high, before beginning to distinguish the background
