>>1007740Box modelling only *feels* slower initially. Because you're doing the work of retopology up front. Which front-loads the process with a lot of problem solving. Whereas sculpting makes the beginning process smoother, since you can turn your brain off, and just mush the geometry around.
However, as the box modeller comes to solve the geometry, the BACK half of the process is a lot easier, because they only need to sculpt their clean topology. And if they need more detail, they just Subdivide.
So it is more or less the same time commitment. Personally, I find box modelling to be better, since I prefer to get the hard part done first. And I also just enjoy solving topology like a puzzle. I don't like work where the tedious part is at the end. So retopology is really annoying to me. It reminds me of my 2D work. Where I did all the fun sketching first, and then I have to follow the fun part with the CHORE that is inking. I hate that.
But yeah, I think that it comes out to about the same amount of time. Once you understand the principles of topology.
