Auto-Tag Regions

Auto-Tag Regions automatically assigns Protect, Focus, and Transition tags using simple geometry heuristics.

This feature is intended for speed, especially in batch workflows.

How it works

Auto-tagging analyzes mesh geometry and assigns regions as follows:

Protect (automatic)

• Faces touching UV seams
• Faces touching sharp edges
• Faces adjacent to edges above a curvature threshold

Focus (automatic)

Planar areas with low curvature are tagged as Focus and treated as safe zones for aggressive processing.

Transition

Any face not classified as Protect or Focus is treated as Transition.

Key settings

• Curvature Angle: lower values protect more of the mesh.
• Planar Angle: controls how strict planar detection is.
• Clear Existing: clears existing tags before auto-tagging.

When to use auto-tagging

• Large asset libraries
• World-building workflows
• Assets where manual tagging would be too slow
