I heard about this technique on a youtube video but when i tried to replicate it it just doesn't work. Essentially the technique consists in model different hard surface parts and then smoothly join them together only with the shrinkwrap modifier instead of boolean the parts and retopologize everything. Here the video, the technique i'm talking about is at the min 16:04

I tried but the final result it wasn't like in the video despite having followed the same process that is just apply the shrinkwrap. Does someone know anything about it? .
