UV
The UV panel provides options for setting the target UV map, removing unused UV maps, or creating new ones using Blender's Smart UV Project.
When baking an object without a UV map, one will be created automatically using Blender's Smart UV Project, based on the settings specified in the panel below.
Target UV
The target UV option provides an easy way to select the UV map to which the textures will be baked. You can choose from three options: active, render, and set.
When active is selected as the target UV map, the textures will be baked onto the currently selected UV map.
The actively selected UV map is indicated by a blue highlight.
When render is selected as the target UV map, the textures will be baked to the set render UV map.
The render UV map is indicated with a white camera icon in the right.
When the target method is set to set, the name property is used to determine which UV map to use. The name can be set in two ways, one is selecting it from the existing options.
The sown UV names are shown based on the viewport selected objects' UV maps.
The target UV map name can also be entered directly into the input field.
The set target name must exactly match the UV map's name, including case sensitivity.
If the set target UV map is not found, the render UV map will be used.
Remove Unused
When this option is enabled, all unused UV maps of the final object will be deleted, leaving only the UV map used for the textures, whether it is the render, custom, or active target UV.
Overwrite
This option allows the target UV to be overwritten using Blender's Smart UV Project, similar to how a new UV is created for objects without one. The original UV data will not be preserved and will be lost, use this option with caution.
Smart UV Project
Blender's Smart UV Project provides a quick and easy way to create UV maps for objects with minimal effort. A UV map is automatically generated for objects that have none, or when the custom target UV map is not found.
