Advanced UV Maps

Advanced UV Maps section created to have quick access to Object Data Properties — UV Maps. It allows to select the active, add, remove, and rename UV Maps from the list.

If more than one object is selected, you can synchronously work with UV maps of the selected objects.

Advanced UV Maps List

The list can work in two modes:

• Multi object mode
• Single object mode

List Description

List Color	Individual for every column
Default color	All selectected objects has the same active UV Map, render, same position in the list
Red color	At least one object differs with one of the UV Map parameters

1. Active UV Map status
	UV Map is active
	UV Map is not active

2. UV Map name
Name is highlighted	All selected objects have UV Map with the name
Name is grayed out	At least one object from selection does not have UV Map with the name

3. UV Map count and position status
First or single digit	Number of objects that have UV Map with the selected name
Second digit	Selected objects count

4. Active Render UV Map status
	UV Map is active for render
	UV Map is not active for render

UV Maps Status Detection

Advanced Maps system detects synchronization status of all UV Maps in the selected objects. It is possible to disable some parameters which are not neccessary for you to detect.

Set Active UV Map

Active UV Map can be changed either by clicking in the list or by assigning hotkey which will change active UV Map according to its index in the list.

Setting active UV Map by hotkey

---

Sync Seams by UV Islands

When changing the UV Map, seams are updated according to the UV islands present in the map.

---

Duplicate Active UV Map

Duplicate the active UV Map or create a new one depending on the operator’s properties.

Remove active UV Map

---

Rename UV Maps

Rename UV maps of selected objects

• UV Maps source - Rename UV maps mode
  • Selected - Operates on the currently selected UV Map items in the list
  • All - Operates on all UV Map items in the list
• Find - The text to search for in names
  • 1) if text is empty then all name will be renamed
  • 2) if ‘Use Regex’ is set then text must be a valid regular expression
• Replace - The text to replace for in matching names found from the ‘Find’ text
• Show Replace Templates Settings - Show list of template names to rename UV maps
• Match Case - Search results must exactly match the case of the ‘Find’ text
• Use Regex - Replace by regular expression in the ‘Find’ text
• Generate Template Names - Rename UV maps from replace preset templates
• Counter - Integer value will be added to the end of the name
• Start from - If Counter property is used, integer value will be started from this value
• Preview - Preview the generated name

Rename UV Maps

Generate UV Map names from template

If you have naming convension for UV Maps in your projects, you can create template preset and quickly rename all UV Maps in one click

UV Map naming preset

---

Sync UV Maps

If your model requires UV Maps to have the same postion, name, active or render status you can synchronize them

---

Copy UV / Paste UV

Allows transferring the UV coordinates between UV Maps.

Example showing how to copy and paste UVs

Copy UV

Copy the UV coordinates of the selection.

Paste UV

Paste the UV coordinates.

---

Adv UV Maps Tools

Clean UV Maps

Remove all inactive UV Maps.

Clean UV Maps

---

Set UV Map Name by Index

Set UV Map name by its Index in the list.

Set UV Map name by index

---

Transfer UV

Transfer UV panel

Example showing how to transfer UVs

Transfer Modes
Matching geometry	Objects must be of type mesh and must have a matching topology
Advanced	Transfer UV maps by generating an interpolated mapping between source and target mesh elements
Layout	Transfer layout of UV maps from active to selected meshes

---

UDIM tools

UDIM workflow is a special workflow that allow to spread UV islands across several different textures of the model.

---

Fill Tile

Fill active UDIM tile with a generated image

• Color - Default fill color
• Width - Image width
• Height - Image height
• Alpha - Create an image with an alpha channel
• Generated Type - Fill the image with a grid for UV map testing
  • Blank - Generate a blank image
  • UV Grid - Generated grid to test UV mappings
  • Color Grid - Generated Improved UV grid to test UV mappings
• 32-bit Float - Create image with 32-bit floating-point bit depth

---

Add Missed

Create the missing UDIM Tile at the Island location.

• By Selection - Use selection to determine where where UDIM tile will be created
• In order - Create all the missing tiles in order until it reaches the last missed tile with the selection

• Fill - Fill tile with settings below

• Color - New tile color

• Width - Tile width
• Height - tile height
• Alpha - Create an image with an alpha channel
• Generated Type - Fill the image with a grid for UV map testing
  • Blank - Generate a blank image
  • UV Grid - Generated grid to test UV mappings
  • Color Grid - Generated Improved UV grid to test UV mappings
• 32-bit Float - Create image with 32-bit floating-point bit depth

---

Set Active

Set the active UDIM Tile based on the selection.

---

Remove Active

Remove the active UDIM Tile

---

Select in Active

Select Islands in bounding box of active UDIM Tile or UV Area

---

Move to active

Move islands to active, or UDIM Tile defined by number
