It’s a tough question because the answer could be different depending on the situation. But I’ll try to answer generally:
If I were building a lo-poly car that needed to look detailed and realistic, I most likely would not sculpt it – unless it was a concept vehicle. But I probably would model it high quality for subdivision smoothing. Then I would retopologize the high quality into a lo-poly model and bake maps similar to the way I did in this course.
I hope thats helpful..
