Mastering UVLayout : Comprehensive Tips and Tricks from the Author

Show overview

[edit] The Core Mechanic

I'll be saying "Flattening" a lot, so here's a quick look at what I mean by that exactly.

Knowing whats going on behind the GUI can only help. Rubber ball demo.

explain heat map, red compression (texture stretched), blue tension (texture squashed)
seams vs distortion

[edit] Setting Up UVLayout

ping main gui for position and 3D window size
floating panels, how to pin
preference for restore GUI panels

other preferences
select Edit LMB pick style
select Save Auto Save

Load file, remembered folders,
also Dir button under Windows

explain kbstate ... shows hotkeys being used.
not so much for live, but when you look back at the recording.

[edit] Cutting

There's more than one way to skin a cat (apologies to cat lovers).

It doesn't have to be perfect first time. Its a process of discovery ... you can try out different schemes. Cut, flatten, see how it goes, then adjust seams by detaching and welding.

Even if the plan is for a single piece "pelt" layout, better to cut and flatten many pieces, optimize them for minimum distortion, then join them back up again.

If you're really happy with how a piece is looking, then just use B key over join, not general optimize.

turn on D drag mode

killeroo example, legs separate or joined etc HERE preview uvsets There is no one perfect solution. Even for the one object, there can be UVs for diffuse color mapping, normal maps, lightfield maps, particle (hair) seeding.

Chassis sample, segment threshold
couch, G key, facing, and other rectangle selects.
plyedit preview for polygon select

[edit] Flattening

difference between F, Space-F, Shift-F, B, and Run All in optimize
plus Live editing
here look at slow smooth optimize preference
also look at defining F1 for Run All / Edit -> Settings

[edit] Welding

often easier in 3D view,
LMB select in uv view, then home/. in 3d view to locate
use M, or Shift-M
green select and move and rotate before weld
look at Segment Fast Weld option

[edit] Kinks

What they are, why the occur, how to get rid of them.

Ctrl-Shift MMB drag
Shift MMB drag
Shift B

Internal kink

can check with Optimize Overlap detection
use 4 to shrink a bit, and then B brush
turn on display4/5

[edit] Geometry to UVs

The relationship between the flattened shapes and UV coordinates, and how that impacts on other tools such as scaling and packing.

so don't scale shells up and down to fit UV square, move square around to fit shapes.
this maintains texture density across the loaded object,
also across all assets but fixing the UV scale.
so use auto fit, or probably pack.
having said that, there are tools for varying the scale, hand example.

[edit] Green Balance

Where you need to use it. plugins

select already flattened, click green balance
select rest, rescale U & V

[edit] Advanced Packing

continue with leon and cube file

pack selected only
pack quality
turn on coverage %
rotate with 0, whats that?
try wrapping

[edit] Subdivision Surfaces

Why they need special handling.

[edit] Obscure Tools

Niche usage, but handy to keep in mind.

Camera scaling
probably in combination with render repaint

Reshape (eg Phileroo),

[edit] Easter Eggs

F8, F9, UV Sets?

[edit] Pattern Making

Costume. Tip: Use Segment tool.

load edit01.uvl
triangles better than quads, less ambiguity
use segment with 0 degree
set scale to size of paper/material
if not square, make b/w mask image
pack with no resize and mask on
folded aluminium face test
