Maxscript Bits & Tricks – Randomize Objects, Colors & Materials in 3ds Max

Bring more life and variation into your 3ds Max scenes with just a few lines of Maxscript!

In this edition of Maxscript Bits & Tricks, you’ll learn how to quickly randomize the position, rotation, wirecolor, and materials of selected objects.
Perfect for creating more natural, less mechanical arrangements in ArchViz, motion graphics, and product visualization projects.

Code snippets

1. Randomize position and rotation of selected objects

Move and rotate selected objects randomly to create more natural distributions.
This script supports 3ds max groups.

for obj in selection where obj.parent==undefined do (
    rPos = random -3.0 3.0
    rRot = random -20.0 20.0
    move obj [rPos, rPos, 0]
    rotate obj (eulerangles 0 0 rRot)
)

2. Randomize wirecolor of selected objects

Assign random wireframe colors to each selected object, making it easier to distinguish them in the viewport.

for obj in selection do obj.wirecolor = color (random 0 255) (random 0 255) (random 0 255)

3. Swap materials among selected objects

Mix up the materials of the selected objects randomly without repeating.

selArr = selection as array
matArr = for obj in selArr collect obj.material
for obj in selArr do (
    idx = random 1 matArr.count
    obj.material = matArr[idx]
    deleteItem matArr idx
)

Why use randomization scripts?

  • Add natural randomness to scenes quickly
  • Create more believable and organic object arrangements
  • Speed up look development for ArchViz, design layouts, or product setups
  • Simplify creative variations without manual tweaking

Maxscript Bits & Tricks – Smart Layer Hacks in 3ds Max

In this episode of Maxscript Bits & Tricks, we’ll take a look at some handy Maxscript snippets to help you organize your 3ds Max scenes more efficiently using layers.

Layers are a great way to group, control, and clean up complex scenes — but often, things end up scattered across random layers or grouped in ways that make no sense. These small but powerful scripts will help you fix that in seconds.

Let’s get started!

Code snippets

1. Move all lights and cameras to the Default layer

Sometimes cameras and lights are scattered across various layers, especially when importing scenes from external sources or merging multiple files. Use this simple line of code to send them all back to the “Default” layer:

for o in objects where (superClassOf o)==light or (superClassOf o)==camera do (LayerManager.getLayer 0).addnode o

2. Move all VRay proxies to a new layer

Keeping your heavy VRayProxy assets organized in a dedicated layer is a great way to manage scene complexity. This snippet finds all VRay proxies in the scene and places them in a newly created layer called “VRay_Proxies”:

lay = LayerManager.newLayerFromName "VRay_Proxies"
for o in objects where classof o == VRayProxy do lay.addNode o

3. Hide all layers except the ones of selected objects

Need to focus only on what you’re working on? This script hides every layer in the scene except the ones where your currently selected objects are. Ideal for isolating working sets without changing visibility layer by layer.

arr = for o in selection collect o.layer.name
LM = LayerManager
for i = 0 to LM.count - 1 do (
    lay = LM.getLayer i
    lay.isHidden = (findItem arr lay.name == 0)
)

Why use these layer scripts?

  • Quickly organize imported or messy scenes
  • Simplify your Layer Manager
  • Focus only on what matters in complex projects
  • Save time in lighting and layout workflows
