For a scene lit by a wood fire, even though the fire itself would be added in post-production, the lighting had to be done within the 3D software in order to accomplish that vibrance of lights and shadows in the ambience. I put various point lights where the wood fire would be, each light with a different tone and intensity, moving at different speeds on a random way but within a specific quadrant for each light. These are the test that I made adjusting these variables until I got a satisfactory outcome.
