Round Edges


The Round Edges node rounds off geometry edges by using a shading effect instead of creating additional geometry. It’s best used for rounded edges that will appear small in the final render. Round edges attributes are built into most of the Octane material nodes, however, there is a dedicated node for rounded edges as well (figure 1).

Round Edges Attributes

Mode - The Fast mode uses the rounding method introduced in OctaneRender® v3. The Accurate mode produces better-looking results, but may be slower. Accurate mode can select the affected edges by using the Concave Only or Convex Only options.

Radius - The rounded edge's radius.

Roundness - Controls the rounded edge's shape. A value of 1 is completely round, while 0 is a chamfer.

Consider Other Objects - Controls how rounded edges are applied to different objects. When enabled, intersections between different objects are rounded. When disabled, only the current object is considered.

Samples - The number of rays to use when sampling neighboring geometry.
