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.

Parameters

    • Compatibility version - The Octane version that the behavior of this node should match.
    • 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 Accurate Concave Only or Accurate 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.
    • Samples - The number of rays to use when sampling neighboring geometry.
    • 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.
