UV Editor

发布于：2024-09-04

Purpose：

Edit and export UV baked texture for clothing models. When performing secondary processing of the model in third-party software, UV baked texture can be used as a material addition to improve the efficiency of material replication for the model.

Operation Path:

Tools ▶UV Editor

Currently Previewing the Displayed Texture		Click the dropdown menu to switch the type of texture shown in the current preview, including: Base Color Map, Normal Map, Roughness Map, Metalness Map, Opacity Map, Displacement Map, and UV Grid Map.
Layout		Click to Auto-Arrange UVs
Zoom	Scale to 0–1	Arrange the selected UVs into the 0–1 coordinate space
	Texel Density	Scale the UVs to the specified texel density. Users can manually set the UV scaling size. The eyedropper tool can read the UV size of the selected pattern piece.
Baking		Click to enter the Bake Texture Settings
Sync with 2D		After clicking, the textures will be arranged according to the pattern layout in the 2D window.
Move		After clicking, you can manually edit the UV layout. You can quickly move selected pattern pieces to other tiles or make fine adjustments to their positions. This is mainly used when arranging textures by quadrants, allowing you to move the texture to the desired quadrant.
Checkerboard Pattern		Apply the checkerboard texture to the UV grid. This helps detect texture distortion, ensure consistent texture scale, identify texture seam locations, and visualize the resolution across different UV islands to optimize texture quality.
Settings		For details, refer to the table at the bottom of the article.

Supports displaying a checkerboard in the UV editor

Apply the checkerboard texture to the UV grid.

Value of Use:

Check the quality of the UV unwrap
Detect texture distortion
Ensure consistent texture scale
Identify texture seam locations
Visualize resolution differences across UV islands to optimize texture quality

Black & White Checkerboard

After selecting Custom Checkerboard as the type, you can set the checker size.

The default size is 64, and the supported values are: 32, 64, 128, 256, 512, 1024

(these numbers represent the number of squares along one edge).

Custom Checkerboard

After selecting Custom Checkerboard as the type, you can add your own checkerboard image to display a customized checkerboard pattern.

Settings	Options	3D Trim UV Layout	Bake trim textures together with garment pattern textures to unify material processing. Each trim texture is a complete square unit and cannot be split into separate assets. When enabled, trims can be edited and arranged together with the garment. If not enabled, trims will require separate texture assignment in third-party software.
		Display the quadrant where the UV is located	Helps users identify whether any pattern pieces extend beyond quadrant boundaries or check if any pieces are missing.
		Bake the opacity map into the texture	When “Bake Opacity Map into Texture” is checked, the transparency information will be included in the final texture.	If “Bake Opacity Map into Texture” is not checked, the final texture will not include any transparency information.
		Collision Detection
	Layout Settings	Supports rotating UV arrangements	When enabled, UVs can be rotated by 90°, 180°, or 270° to improve layout efficiency.
		Padding	“Padding between UVs” and “Margin to Borders”: 0.01–0.05 (If 0.05 cannot be achieved during layout, the system will arrange using the maximum achievable padding.)
		Region	Supports arranging UVs within the target quadrant range
		Arrangement Method	Default rule-based layout
			Layout by Fabric Type: Pattern pieces using the same fabric are prioritized to be placed together, while other pieces fill the remaining spaces.
			Layout by Pattern Group: Pattern pieces belonging to the same group are prioritized to be placed together, while other pieces fill the remaining spaces.
