It was requested quite a lot, so I put together 10 base UV examples I use, starting from how to set up the Grid to A full assets Layout.
Everything I do is in base Maya 2018 so there is no plugins although I am sure there are quite handy plugins out there. There Is also many ways to do things and many programs to do UVs in, this is just generally how I tackle shapes. The videos are quite basic and to the point but even UVing the most complex shapes stems down to breaking the shape up in to its most basic forms and tackling them individually.
Use Shift Right Click and Ctrl Right Click to access the sub menus I use, they change based on UV, edge or Face selection.
In example 10 I am sure people will comment on the wasted space, but in film UDIM count is rarely an issue for us while updating a model after its even textured is common. so flexibility, organization and texturing ease over a few more pixels of resolution.
Any questions comment below.
