Description

Contact Mask

A geometry-aware proximity mask — it lights up where a surface gets close to other stuff in the scene, so you can pool grime, darkening, snow or AO right into the contact seams. It's a paste-in node group, not a material: it hands you a clean 0-1 mask (and an optional contact normal), and you multiply that into whatever you want to localize.

Under the hood it reads the global mesh distance field — the engine's running tally of how far any point is from the nearest surface — with a single DistanceToNearestSurface tap at the shaded pixel. That distance gets remapped to a soft mask: 1 when this surface is right up against other geometry, fading to 0 by Contact Distance away. Crank Contact Distance up for a broad ambient-occlusion-ish pool, drop it for a tight crevice line. Sharpness bends the falloff — high pinches it to a crisp grime seam, low spreads it into a gentle gradient. There's no Time anywhere in here, so it's TSR-safe, and it's all native nodes, no HLSL.

This is the geometry-aware cousin of a blob-shadow decal: a blob shadow is a flat projected shape that knows nothing about the world, whereas this reacts to the actual meshes nearby. Set props down next to a wall and the grime finds the corner on its own.

It's a node group with no Material node in the paste, so the hookups are on you (downstream links never survive a T3D paste):

Settings you have to set

  • Project Settings -> Engine -> Rendering -> Generate Mesh Distance Fields = ON, then restart the editor. This is non-negotiable — without it the distance field doesn't exist, DistanceToNearestSurface returns a big constant, and the mask reads flat 0 everywhere.
  • Wire the Result node (in the frame labelled Result -> multiply into grime / darkening / snow / AO) into whatever you're localizing: Lerp(clean, grimy, alpha=Result), or multiply it onto a darkening tint feeding Base Color, or use it as the alpha that brings a snow/water layer in at object bases.
  • Material Domain stays Surface. Shading model and blend mode are whatever your host material already is — this tool just produces a scalar, it doesn't care.
  • Meshes that should cast into the mask need Affect Distance Field Lighting on (that's the default). Distance fields are coarse, low-res voxels, so this is for soft, large-scale contact — not pixel-sharp edges.

Params:

  • Contact Distance — the world-unit reach. The distance to nearby geometry at which the mask fade
