oh, the render look less time than usual because,, well,, basically it's a low quality render xDD
sorry no.. i made this model with a friend and we've decided not to share it with anyone.. but you can make it yourself if you want.. all we did was sculpt G3F's face as close as possible to Tzuyu's appearance then make a deepfake model to finalize the look.
so,,, what? i'm using raytracing! those videos are obviously using rasterization... i can do rasterization if i wanted to, it's super easy... i just don't dude...
