UV Deformer is a Blender add-on that introduces multi-instance lattice deformation capabilities directly within the UV Editor. It allows users to adjust and warp UV maps using a customizable lattice grid, making it easier to correct distortions or fine-tune specific areas of a UV layout.

The tool features an interactive 'Warp Mode' where users can select and drag individual or multiple lattice control points to deform the underlying UVs in real-time. It supports dynamic U/V grid resolution adjustments (ranging from 2 to 10 divisions) and allows for multiple independent lattices per mesh for layered deformations. Users can manage visibility, bake changes, or discard lattices through a dedicated N-panel interface in the UV Editor.
