Reliable UV transfer across meshes and LODs — without re-unwrapping
[Disclaimer] Required Plugin Dependency: GeometryProcessing
This plugin provides a robust, production-ready workflow for transferring UV attributes between meshes and LODs in Unreal Engine. It is designed for technical artists and developers who need precision, repeatability, and control when working with evolving geometry.
Whether you are fixing broken UVs, synchronising LODs, or reusing high-quality unwraps, this tool eliminates hours of manual cleanup.
Please read the documentation and examples carefully to ensure this is the right tooling for your use cases. This is a transfer from an already unwrapped mesh layout to others only; there is no functionality included to unwrap or auto-unwrap a mesh.
The tooling cannot adjust unreal-generated LOD UVs or Lightmap UV layouts. It can use them as the source to gather data from, but it cannot write new UVs to it. Error logs will be returned when this is the case. (Documentation)
What This Plugin Solves
Transfer UVs between different meshes
Propagate UVs across multiple LODs
Preserve UV consistency during mesh iteration
Avoid costly re-unwrapping and rebaking
Handle mismatched topology safely and predictably
Built for real production constraints — not idealised meshes.
Core Features
Mesh-to-Mesh UV Transfer
Transfer UV attributes from a source mesh to a target mesh, even when their topologies differ.LOD-Aware Transfers
Transfer UVs from a specific source LOD to:a single target LOD
all LODs in the target mesh
Multiple Transfer Modes
Choose between precise, single-operation transfers or automated batch-style workflows.Non-Destructive Workflow
Control exactly which UV channel is written — existing data is preserved unless explicitly overwritten.
Transfer Modes Explained
Execute Single UV Attribute Transfer
Perform one explicit transfer with full control over all parameters.Simple UV Attribute Transfer
A streamlined option for common use cases where meshes are already well aligned.Mesh to Mesh – Transfer All UV Attributes
Copies all UV channels from source to target in one operation.Mesh LOD to All LODs – Transfer UV Attributes
Ensures UV consistency across the entire LOD chain using a single source LOD.
