Hello everyone, I'm having a problem with lights...If you look at the first picture I have an area light on a flag....I am happy with this. Now without changing any settings....I just turn ON the visibility of the buildings in the background and the quality of the light is terrible (pic 02) keep in mind I have changed nothing except turn on the visibility of buildings....Can anyone let me know why this is happening? I am using c4d18 and octane 3.07-R2 and using GI Diffuse. Thanks!
