Surface Curvature Shader [V1.01, C4D R12 - R15, Win]


  • Create dirt maps of all kinds! With the full angle control combined with wind, you can distribute dirt, scratches, rust or abrasion regions, wherever you need them.
  • Some more buzzwords: Hardsurface, Organic, Weathering, Morell
  • No UV mapping necessary, very useful for complex objects and the use of procedural textures.
  • With a little tweaking, effects close to Ambient Occlusion or Subsurface Scattering, can also be achieved.
  • For artistic use with deforming objects (animations).

Two examples by John Strieder:



Control: Separate convex and concave controls!

Individual controls allow for maximal freedom in selecting the mapping range by curvature.



More Control: Automatic/Manual Range Clipping, Separate/Common mapping Curves!

 Automatic Mapping will choose the maxiumum values for the clipping automatically or the values can be entered manually.




Fast: Takes advantage of all your processors!

This example was rendered in the Cinema Editor with only the Curvature Shader in the Luminance Channel with an object containing 10 mio (!!) polygons. Two blur passes are done too. The time needed on a twelve-core machine is 6 seconds (5 are needed for Cinema to prepare). If that speed is not yet enough, you can always just bake your map!



Wind and Blur: For smooth and windy results!



Fill 'Hole' Feature: Apply fixes for small problems or use it as another tweak in the mix with the other parameters!



Universal: Works on anything that finally creates polygons, including Hypernurbs!
