Replicate3D
Instance geometry on points or particles
Replicates a 3D object across incoming particles or points, with controls for alignment, color, transforms, time offset and jitter.
Replicate3D
DaVinci Resolve · Fusion
Replicate3D turns a point/particle distribution into a layout for repeated 3D geometry, which is useful for crowds, arrays and procedural structures.
Overview
What Replicate3D does
Replicate3D turns a point/particle distribution into a layout for repeated 3D geometry, which is useful for crowds, arrays and procedural structures.
Mental model
Think of the incoming points as sockets and the input 3D object as the item plugged into every socket.
Common uses
Instance geometry on particle positions
Build procedural object fields
Create repeated 3D elements with per-point color
Align objects to point orientation or motion
Flow anatomy

Practical setup
A reliable workflow
- 1
Create the source 3D object.
- 2
Create or import a suitable point/particle distribution.
- 3
Connect both to Replicate3D.
- 4
Choose Input Mode and Alignment.
- 5
Add jitter only after the basic distribution is correct.

Troubleshooting
Common mistakes
Expecting Replicate3D to create points by itself.
Using a very dense point source and overloading the 3D scene.
Ignoring alignment and getting randomly oriented copies.
Adding large jitter values that destroy the intended distribution.
Production notes
Practical tips
Optimize the point source before optimizing the replicas.
Use color transfer when point colors already encode useful variation.
For simple linear repetition, Duplicate3D is often lighter and easier.
