3.3 Lighting Analysis


The Lighting Analysis render element allows you to accurately measure light light levels in a 3D scene.

  • Let’s add it from the render elements list
  • Before starting render you might want to go through your glass materials and set the refraction “Affect channels: All”. This way you will be able to have information in the lighting analysis for areas that are behind glass objects
  • Press render and wait until the image is relatively noise free
  • Take a look at the “VRayLightingAnalysis” render element
  • At this point it doesn’t give a lot of information
  • We need to adjust its range to gather more details
  • Simply click “Update…” button to recalculate the lighting analysis
  • There is one more way to display the data - check “Grid overlay”
