1.25.3 Fine-tuning Global Illumination

 

 To change the number of photons used to compute the local intensity of global illumination, specify a globillum accuracy (and optionally a maximum radius) in the options. For example,

 

globillum accuracy 300 2.0

 

 

The default number is 500; larger numbers make the global illumination smoother but increases render time. The default radius depends on the scene extent.
