Scene Ambient Light

Post by CADMAN »

We started adding LuxCoreRender API to a Home Design application that is currently using Siemen's Lightworks which allows defining a scene ambient light intensity.

Is there a scene ambient light setting or a recommended "default" lighting configuration.

Thanks

Ambient light usually was, in very old ray tracing terms, a constant illumination added to any visible point. It was a fake, a trick used many years ago to give the feeling of global illumination and to not have pitch black shadows. Is what Siemen's Lightworks means with ambient light intensity ?

LuxCore computes true indirect illumination so it doesn't have this kind of fake feature. I assume you can just ignore the Siemen's Lightworks scene ambient light intensity setting (because you will have true indirect light contribution with LuxCore instead).

Otherwise you could use a LuxCore infinite constant light source with the Siemen's Lightworks scene ambient light intensity setting (note: it will contribute to an indoor scene only trough windows and other wall holes).
