Ok, im trying to wrap my head around the 2 different options for UV layout.
UV master. Im getting bad results when trying to unwrap a cylinder with the caps cut off.
UV MAP. Way better results, tight seams etc. What is the difference? in the UV MAP options, I only press Morph UV, I dont go into the " CREATE " features. . .
You have done 2 diferent UV layouts for this reason they look different
In the first case you did with UV master
In the second case you didn´t create any new UV layout because you are using the own cylinder UV´s. The cylinder comes with that UV layout. So inside Zbrush all primitives converted to 3DMesh has Perfect square UVs premade
Hope this makes sense
Thank you very much for your reply.
