Tag Properties
This option should be active especially when importing scenes from other applications. This prevents the UV mesh from mistakenly being edited by BodyPaint 3D's UV editing tools.
More about working with UVW coordinates can be found under mapping types (projection).
Enable this option if you want to transfer UV coordinates from other objects as described under Transfer Values .
An additional Transfer Values tag will be displayed that shows the VAMP (now Transfer Attributes) settings.
