Overview


Edges achieves an effect similar to wireframes. Since it is a texture, it allows for interesting effects that are not possible with the standard materials. The texture can also be used as a bump map to produce a "round corners" effect for mesh objects.

 

 

Parameters


 

 

Edges Color  – Specifies the color of the edges.

Background Color –Specifies the color of the faces.

Width Unit Type –Specifies the unit of measurement for the thickness of the edges

World units – Thickness of the edges will be measured in world (scene) units.
Pixels – Thickness of the edges will be measured in pixels.

Width (Scene Units) – When the Width Unit Type is set to World Units, this parameter specifies the thickness of the edges in world (scene) units.

Width (Pixels) – When the Width Unit Type is set to Pixels, this parameter specifies the thickness of the edges in pixels.

Show Hidden Edges – When enabled, this will render all edges of the object. When disabled, only edges marked as "visible" will be rendered. For more information, please see the Show Hidden Edges Parameter example below.

Show Subdivision Edges – When enabled, edges generated by displacement mapping or render time subdivision will be visible.

 

Round Edges


 

Same Object Only – When enabled, the rounded corners will be produced only along edges that belong to the same object which has the map applied. When disabled, rounded corners will be produced along edges formed when the object with the edges map intersects other objects in the scene. For more information, please see the Same Object Only Parameter example below.

Corners – Specifies which corners should have rounded edges applied to them. For more information, please see the Corners Parameter example below.

Convex and Concave – The effect is applied to both convex and concave edges.
Convex only – The effect is applied only to convex edges.
Concave only – The effect is applied only to concave edges.

 

 


 

Example: Show Hidden Edges Parameter

 

 

Hidden edges is off

 

Hidden edges is on

 

 

 

 




Example:Same Object Only Parameter


In this example, the cube and the cylinders are separate objects in the scene.

 

 

Consider same object is on. The rounded corners effect
is applied to each object individually.

 

Consider same object is off. The rounded corners effect
is applied between the different objects.

 

 

 


 

Example: Corners Parameter

 

 

Convex & concave corners

 

Convex corners only

 

Concave corners only

 

 

 

Multipliers


 

 

Mode – Specifies the multiplication mode of the colors. 

Multiplier – Multiplies the RGB numbers for each pixel of the top layer with the RGB number of the corresponding pixel from the bottom layer. The result is a darker picture. 
Blend Amount   Takes each pixel from the top layer if present. Otherwise the bottom layer is used.

Edges Color – Controls the intensity of the edge color.

Background Color – Controls the intensity of the background color.

 

Notes


 

  • When applied to displaced or subdivided objects, the Edges will normally show the edges of the original mesh:

 

 
 

  • Edges cannot simulate outlines on the objects; you can use Toon | MtlToon to add outlines.
  • Currently, when used as a bump map in glossy materials with Blinn or Ward BRDF, Edges may lead to dark edges; to avoid this, use the Phong BRDF instead.
