C4D users outside of this forum vehemently defend C4D’s UV editing tools but truth is they’re pretty bad. Simple click-and-drag a polygon? Watch it slip and slide all over the place. Basically a very shoddy tool and mostly unusable outside of automatically laying out hard-edged models.
On the other hand 3D Coat is an amazing UV unwrapper, especially for organic forms. It’s like 3DS Max and then some again. There’s a demo that you can try.
There’s nothing wrong with this workflow, really. In fact you might be less likely to prematurely start UV unwrapping by mistake.
