Controls / Number of Lines
Sets the number of lines.
Procedural ribbon geometry
Generates strip-like 3D geometry for bands, trails, swooshes and flowing motion graphics.
Generates strip-like 3D geometry for bands, trails, swooshes and flowing motion graphics.
Overview
Generates strip-like 3D geometry for bands, trails, swooshes and flowing motion graphics.
Think of a long strip of paper in 3D whose width, twist and shape can be animated procedurally.
Flow anatomy
The port structure shows how this node fits into a Fusion graph.
Incoming 3D geometry or scene branch processed by the node.
Processed 3D geometry or scene data for Merge3D, Renderer3D or another 3D node.
Inspector
Start with these controls before reaching for more complicated workarounds.
Sets the number of lines.
Sets the thickness of each line in the ribbon.
Sets how finely the ribbon geometry is subdivided along its length.
Sets the horizontal size.
Rotates the ribbon around its local path/tangent direction.
Chooses how adjacent ribbon segments are joined.
Sets a limit for the working range.
Sets the X, Y and Z components of start.
Sets the X, Y and Z components of end.
Controls whether the object is visible in the rendered scene.
Keeps the object in the 3D scene while hiding it from camera renders.
The object can still be useful for lighting, shadows or other scene interactions depending on the setup.
Controls whether front-facing or back-facing polygons are discarded.
Use face culling to diagnose reversed normals, inside-out geometry or single-sided surfaces.
Suppresses auxiliary 3D channels where the object is transparent.
This keeps Object ID, Material ID, normals and similar passes clean around fully transparent pixels.
Controls whether scene lights illuminate this object.
Controls whether the object casts shadows onto other geometry.
Controls whether the object or material receives shadows.
Treats the object as a matte in the 3D composite.
Use matte objects for holdouts and technical occlusion rather than as ordinary visible geometry.
Selects the 3D blend mode for this renderer.
Chooses how the object is combined in the selected 3D renderer.
Selects the 3D blend mode for this renderer.
Chooses how the object is combined in the selected 3D renderer.
Sets the gain of the effect.
Sets the display length of the normal and tangent guides.
This affects the diagnostic overlay, not the actual geometry.
Shows Normals in the Viewer for setup or diagnostics.
Viewer guides do not normally change the rendered image unless the control explicitly says otherwise.
Shows Tangents in the Viewer for setup or diagnostics.
Viewer guides do not normally change the rendered image unless the control explicitly says otherwise.
Assigns the Object ID written to the render passes.
Object IDs provide a clean way to isolate individual 3D objects after rendering.
Sets or exposes the material used by the 3D object.
Standard Fusion node settings for processing, masks, blending and animation.
Practical setup
Create or import the geometry that Ribbon3D will work with.
Insert Ribbon3D at the point where the 3D behavior should change.
Inspect the Ribbon3D result in a 3D Viewer with a simple camera and light before building the final rig.
Keep transforms, materials and Ribbon3D-specific overrides in clearly separated parts of the scene.
Merge the finished Ribbon3D branch into the scene and render it through Renderer3D.
Examples
Ribbon3D processes a geometry branch before it enters the main scene.
Ribbon3D is isolated in its own branch for easier debugging and reuse.
