Falloff shapes, Freeze, Realize.
Falloff #
One Falloff component. The Add menu offers presets of its Shape: Linear, Sphere, Box, Cylinder, Radial. For how constructors read a Falloff, see Falloffs and Names.
| Control | What it does |
|---|---|
| Falloff Name | The name constructors look for |
| Target | Pieces, Mesh Points or Both |
| Vertex Group | For Mesh Points. Empty uses the Falloff Name |
| Shape | Sphere, Box, Cylinder, Linear, Noise, Object, Spline, Vertex Map, Radial |
| Blend | Normal, Add, Subtract, Multiply, Max, Min |
| Opacity, Invert | How strongly this layer applies, and flipping it |
Shapes #
| Shape | What it does |
|---|---|
| Sphere, Box, Cylinder | A volume: 1 inside, fading to 0 at the edge |
| Linear | A gradient along the chosen direction |
| Noise | Animated noise (Noise Scale, Speed, Seed) |
| Object | Falloff from another object’s geometry (Surface, Volume or Points, within a Range) |
| Spline | Falloff from the distance to a curve object |
| Vertex Map | Reads a vertex group or named attribute straight in |
| Radial | Rises by angle around the Falloff’s own Z, with Iterations for pinwheels |
Panels #
- Placement: Position, Rotation, Size, or Use Object to place it with an empty. Show Falloff draws a viewport-only wireframe that never renders. Position Space sets which axes Position uses (below).
- Falloff: Inner Offset, Profile (Linear, Smooth, Ease In, Ease Out, Sharp, Bell, Steps), Remap Min and Max.
- Color: Off, Solid or Gradient. Writes
<Falloff Name> Color. - Source: Source Object, Object Mode, Range, Vertex Map Name, Radial Iterations and Offset.
Position Space #
- Falloff Axes (default): Position moves along the Falloff’s own rotated axes. Rotate the Falloff to match an angled rig, and Position X alone moves it through the rig along that angle, with no X and Y mixing. With no rotation it is identical to Object Axes.
- Object Axes: Position, Rotation and Size use the object’s own axes, so the Falloff is locked to the host’s axes.
- In Falloff Axes the move gizmo is three arrows along the Falloff’s own X, Y and Z. In Object Axes the normal move gizmo is used.
- Older files switch to Falloff Axes when you run Update Toolkit Groups, so a rotated Falloff may move. Set Position Space to Object Axes to get the old behavior back. See Update and Repair.
Helper buttons #
In the Ordimus tab, Falloff Helpers lists the Falloffs, Targets and Splines on the active object. A small empty button next to each places it with an object. Create Falloff Vertex Groups adds the vertex groups that Mesh Points Falloffs need.
Freeze #
Place it below the Falloff it freezes, with the same Falloff Name. It holds the value over time so the Falloff leaves a trail.
| Panel | Controls |
|---|---|
| Grow | Speed, Threshold, Max Distance, Substeps. The value spreads to neighbors |
| Decay | Hold (seconds), Rate (per second) |
| Blend | Blend and Opacity. It holds the Falloff’s color too |
A simulation: play from the start frame.
Realize #
Turns instances into real geometry anywhere in the stack.
- Realize All Levels flattens nested instances. Levels only matters when All Levels is off.
- Instance data is lost. Add an Ingestor after it to get pieces again.
