Unwrap a simple cylinder in 2.8 I am trying to unwrap a basic cylinder to a picture wich has a size of 4096x1080px. 



The UV map is supposed to look like the 64 faces side by side within the boundaries of the image. 

Whatever I try - it never comes to that point. I tried to reset first and than unwrap, to reset and to follow active faces, to pack islands, etc. 

There is one weird (I guess) thing: In pretty much every case the faces are rotated by 90° in the UV map. I don't know if this is related to something...

This is the standard map when I start from scratch and hit 2xU (All 64 faces are vertically squeezed into the boundaries) - I want exactly this - just horizontally:



Any help is appreciated!

Thanks and best.

The simplest way is to generate the UVs at the same time as you create your object. Just enable the Generate UVs box.
