3ds Max Copy And Paste Script

Before diving into the script, we must understand the limitation of the native system. In 3ds Max, when you select an object and press Ctrl+C, you are copying a reference pointer to the object's location in the current scene's memory. When you press Ctrl+V, Max creates an instance or copy of that object within the same .max file.

This works fine for duplicating a chair leg ten times. However, try to open File A (a character model) and File B (a new scene), copy the character in File A, switch to File B, and paste it. It won't work. The clipboard empties the moment you close or switch the active document.

The workaround? File > Import > Merge. While functional, merging is slow. It requires navigating through dialog boxes, searching through object lists, and manually selecting what you need. If you need to copy-paste thirty times in an hour, Merge kills your creative flow. 3ds max copy and paste script

Enter the Copy and Paste Script. This script hijacks the Windows clipboard or creates a persistent memory buffer that survives session changes.

A sophisticated copy-paste script operates by dismantling the scene object into its component parts via MAXScript. In the object-oriented paradigm of 3ds Max, a Teapot is not just a teapot; it is a class instance with properties such as .pos, .rotation, .scale, and .material. Before diving into the script, we must understand

A deep-dive into the code of such scripts reveals a separation of concerns. The script creates a temporary storage buffer (often a global variable or a struct) that holds specific data types.

try
(
    clip = dotNetClass "System.Windows.Forms.Clipboard".GetText()
    json = dotNetObject "System.Web.Script.Serialization.JavaScriptSerializer"
    arr = json.DeserializeObject clip
    if arr.count != selection.count then
        format "Warning: copied % objects, but selection has % objects. Will apply in order.\n" arr.count selection.count
    for i = 1 to (min arr.count selection.count) do
    (
        src = arr.get_Item (i-1)
        tgt = selection[i]
        if src.transform != undefined then
            tgt.transform = arrayToMatrix3 (for v in src.transform collect v)
        if src.mods != undefined then
        (
            for sm in src.mods do
            (
                try
                    addModifier tgt (execute sm.class) -- may fail
                catch()
            )
        )
    )
    format "Pasted onto % objects.\n" (min arr.count selection.count)
)
catch e
(
    format "Error: %\n" e
)

This script lets you copy the transform of one object and paste it onto another. This script lets you copy the transform of

-- Copy Transform Script
global copyTM = undefined
macroScript copyTransform category:"My Tools" tooltip:"Copy Transform"
(
if selection.count == 1 then
(
copyTM = selection[1].transform
format "Transform copied from: %\n" selection[1].name
)
else
messageBox "Please select one object to copy transform from."
)
macroScript pasteTransform category:"My Tools" tooltip:"Paste Transform"
(
if copyTM != undefined and selection.count > 0 then
(
for obj in selection do
obj.transform = copyTM
format "Transform pasted to % object(s)\n" selection.count
)
else if copyTM == undefined then
messageBox "Nothing copied yet. Use 'Copy Transform' first."
else
messageBox "Select at least one object to paste transform to."
)
