Check the box to activate the lights included in the background image. Use the cursor to set the lighting power. Values range from -100 to 100. Clicking on the red diode retrieves the original power lighting.
NB: An HDR Image can be used for the lighting of a scene by itself, without any other light source. HDR images have a greater dynamic range between the lightest and darkest areas of an image.
Tip: An HDRI background can be combined with a Heliodon. As regards Artlantis rendering, this is a way of reinforcing the power of the shadows. As regards Maxwell Render Engine, when using an HDRI background, the light of the heliodon is not taken into account. Maxwell does not need to do this in order to manage the shadows.
The foreground image must have an alpha channel (representing the opacity or transparency of the image). For example, to view the scene through vegetation.
The accepted file formats are tga, tiff, png and psd. If you intend to use the Edit Alpha Channel command, only these file formats will be taken into account: jpg, bmp and png.
