tyBend Modifier

The tyBend modifier is an alternative to 3ds Max’s built-in Bend modifier, that has options for bend segmentation so that you can bend a mesh along any axis and get a smooth/sharp crease that is not dependent on underlying topology.

The tyBend modifier is ideal for creating folding effects, like procedural origami.

tyBend Rollout


  • Angle: the amount (in degrees) to bend around the specified bend axis.

  • Direction: the amount (in degrees) to rotate the bend transform around the specified bend axis.

  • Use vertex selection: controls whether or not underlying vertex selections will affect the bend amount.

Bend Axis

  • X/Y/Z: the axis (of the bend gizmo) around which to bend geometry.


  • Limit effect: controls whether the bend deformation will be limited to a certain distance above/below the bend axis.

  • Upper limit: the amount to limit the bend deformation above the bend axis.

  • Lower limit: the amount to limit the bend deformation below the bend axis.

  • Bend left/right/back/front: these additional limits allow you to control whether bend deformations will happen on either sides of the two auxiliary axes of the bend transform.

Bend subdivision

  • Segments: the number of segments to generate parallel to the slice plane.

  • Render: enables a render-only segment value, for increasing/decreasing segment count at render-time.

  • Weld seams: controls whether the vertices on the open edges of the segment slices will be welded together.

  • Optimize slices edges: controls whether the edges of sliced polygons will be optimized. Enabling this can reduce the vertex/face count of the result, but may prevent some areas of the slice edges from being welded, since adjacent face vertex locations may not match after optimization.

  • No subdiv when angle=0: when enabled, the mesh will only be subdivided when the bend angle is not equal to 0.
