To improve the review process in 3D CGI production for creators, we investigate approaches of analysing a path-tracing render task, due to the stochastic nature of path-tracing. From this investigation we propose a design of a render farm system with additions targeting the review process. From the proposed design, we developed a minimal viable product. From evaluations of the minimal viable product, we find an improved system, to our previously developed render farm system, both in terms of its cost and accuracy. Additionally, we find the proposed system to be controllable and transferable to existing render farms. Thus, we show a system with both potential and attractiveness towards existing render farms, to improve upon the review process for creators.
