Change proportion on base mesh I discovered a video that shows a very quick way to make base mesh (skin modifier as everyone already knows)

but it's a timelapse, so there's no explanation at all.
In 01:00 he starts to scale vertex to change proportion for each part of the body.


the problem is, I don't know how he did it, because I try to scale vertex but nothing happens I used S and alt S.

they made the centre point &quot;root&quot; (for skin modifier) in edit mode, then turned on skin again (but in edit mode still), then they selected all and scaled in &quot;median point&quot; I assume, then left edit etc..  I tried it but am not used to mirror in this way :) So could scale but it was a mess.
