wolf, as usual you take an antagonistic tone with anyone who does not agree with you.

it is my opinion that one man could not do that many FINISHED renders in a year, not in HD quality, it would be pushing it even if each render was preview quality. not if he singlehandedly  built, uv'd, textured most of the models in scene, ran animations , rendered each frame ( 95 per day, finished) did any necessary postwork, edited etc etc.

besides, nobody is required to justify an OPINION to you or anyone else.

( also, as the author stated most of the rendering was done in DS3, and if volumetrics were used in DS3, the render times are horrendous)
