Overview

Bakes convex and concave edge information from a mesh into a UV-space mask.

Material source. Bakes the selected mesh's convex and concave edge response into its UV layout; it has no graph inputs.

Usage

In practice

  • Choose a target mesh, then use the baked mask to isolate convex or concave edges.
  • Feed the mask into Colorize, Mask, or a Material Output channel as required.

Examples

These examples show Mesh Curvature in supplied VFX Loom graph setups. Each graph link opens the corresponding node reference; the explanation below the media is specific to this node's role in that setup.

Material maps and masked detail

A Material graph combines procedural colour, mesh-derived curvature and occlusion, roughness, normal detail, and a layered composite.

How Mesh Curvature contributes

Mesh Curvature supplies an edge-oriented mask from the preview mesh.

Notes / limitations

  • The map is baked into the mesh UV layout and has no graph inputs.
