The tips shared in the thread seems too complicated for me but I am deeply impressed with CeciliaB's post where she put light sources on the floor to simulate light beam spots on the floor. So I tried to follow her tricks by putting several light sources with elevation around 5cm to 40cm, but some of the renders seem to give some desirable effects. Please see attached photos.
The round light patch on the left came from the light source (with 5cm elevation from the floor). It looks too harsh and out of place. Then the light source near the girl's right lower leg gave a black patch on it. Overburned?
Look at the dark patches on the door frame.
Any tips on how to avoid these unwelcome ground level light source reflections?
