It is recommended to open two 3Ds Max windows for convenience. One is for your current project scene, the other is for preparing the model.

  • Create a new scene and open the model. Then click the Apply button on the File tab in the Stock Model Fixer script. All checked options from "Apply to current scene"  will be applied to the current scene.
  • In the Tools tab, if necessary, do Box Trick, Detach Trick, Snapshot, Reset XForm to fix broken model geometry.
  • In the Textures tab, specify the path for saving textures (Copy textures to folder) (for example, a folder with textures of your project) and press Copy Textures. All textures of the model will be copied to the specified location.
  • Copy and paste the model using CopyTo/PasteFrom.
  • Done.
Watch this video with an example of using this script:

Example of usage Stock Model Fixer

Stock Model Fixer has many tools for optimizing and preparing models. Read more about each tab below.


Newer versions of the Stock Model Fixer use the Universal Installer to help you with the installation, as well as create buttons in the Main Toolbar and Quad Menu. Everything is done so that you make a minimum of effort and do not waste valuable time.

Step 1

stock model fixer install scripting run script
Run the installer, just Drag&Drop the StockModelFixer.mzp file into the Autodesk 3Ds Max Viewport.
Or run StockModelFixer.mzp using the Scripting → Run Script drop-down menu.

The entire installation process is in this video instruction. Another script (Prune Scene) is used as an example, but the process is absolutely identical for the Stock Model Fixer!

Installation using Prune Scene as an example (Video)

Step 2

After starting the installer, you will see the following window:
installation wizard s0
Select the interface language, click Next.

Step 3

installation wizard s1
Read and agree to the license agreement, click Next.
(Full information about the Security Policy, Terms of Use and License Agreement is available on the official website Using this script, or any part of it, you automatically agree to all the terms!)

Step 4

installation wizard s2
At this step, you can customize the installation options. For example, where to create a button in the interface (Main Toolbar, Quad Menu, Main DropDown Menu) .
We recommend leaving all the default options and click Next
Below is a description of what each option does if you want to change anything.

Tool Bar (Recommended) - creates a button with an icon on the main toolbar.
Main DropDown Menu - creates a new dropdown menu named 3DGROUND next to the Help dropdown menu with subitem Stock Model Fixer. If other scripts from this site are installed, they will be added to the 3DGROUND dropdown menu.
Quad Menu - creates a new Stock Model Fixer menu item in QuadMenu.

Use HiDPI icons - use (SVG) vector icons for high resolution monitors. If your 3Ds Max is greater than 2018, which has official support for higher resolution monitors, you can enable this option. Icons will work for regular monitors as well as monitors with higher pixel density.
(It should be noted that for some unknown reason, some users (about 15%) may not display HiDPI icons. Therefore, the option is disabled by default - No. You can enable this option, but if your icon disappears in the interface, just reinstall the script with the default option - No)
Setup Options - you can select Install or Remove script.

Step 5

installation wizard s3
At this step, the installer copies all files and creates menu items. You will need to click Yes if the installer does not have enough rights to copy. See screenshot below:
If you click No, there is no guarantee that the script will work correctly and all files will be copied!

Step 6

installation wizard s4
If the installation was successful, you will see the following window. Click Finish to exit the installer.
You can now run the script from the Main Toolbar or the 3DGROUND dropdown menu.

stock model fixer main multi language
In new versions of Stock Model Fixer, support for different interface languages ​​has been added.
Currently the following languages ​​are supported: English, Russian, Ukrainian, Polish, Vietnamese.

You can select the interface language during the installation of Stock Model Fixer or after launching it.

Select your language interface from the Language dropdown menu and the interface will instantly be displayed in the selected language, without having to reopen the script.

The list of languages ​​was not compiled at random. The languages ​​that have made the most purchases have been added.
If you want to see Stock Model Fixer in your native language, buy a license and support the script itself, maybe your language will be included in the next version?!

Grammatical errors and mistakes in translation are not excluded, write in the comments if you find any inaccuracies.
Or, we can provide all the tools you need to edit the language file!

File Tab

stock model fixer tab file
Open the model in a new scene, press the Apply, button so that all the checked options in "Apply to current scene" have been applied.

Remove Animation Keys - removes all animation keys. Usually animation is not needed and this option is enabled by default. 
Disable BackFace Cull Property - disables the BackFace Cull property for all objects in the scene. This makes the Viewport faster.
Enable Renderable Property - Enables Renderable in properties for all objects in the scene. Quite often, you come across such models on 3D stocks in which this property is disabled and you can see this only on the render.
Resolve and Relink Textures - helps to find textures in folders and subfolders of the model and automatically assign new paths.
Remove Empty Objects - removes objects with 0 polygons, empty groups and Particle View objects.
Remove All Layers - removes all layers in the scene and transfers all objects to 0 layer (0 default). If you disable this option, unwanted and empty layers can get in your main project scene and ruin your hierarchy.
Clean Multimaterial - removes unused sub-materials.
Unhide All (Objects/Polys) - makes all objects and object polygons visible.

CopyTo/PasteFrom Section

CopyTo - copies the selected objects.
PasteFrom - pastes the copied objects.
Whichever tab you open, the CopyTo/PasteFrom section will always be available.
Copying and pasting objects works on the same principle as the free script "CopyTo", and is fully compatible with it.

CopyTo/PasteFrom - works between scenes, between different 3Ds Max windows and even after restarting the computer.

Tools Tab

Turbo Smooth

stock model fixer tool tab turbo smooth
Allows you to manipulate TurboSmooth and MeshSmooth modifiers applied to objects.

Iterations: 0 - sets smooth iterations to 0, and activates Render Iters.
Thus, smooth will be visible only on the render and there will be less load the Viewport.

Select - select all objects in the scene with the TurboSmoot and MeshSmooth modifier.
Add - adds a TurboSmooth modifier to the selected object.
Delete - removes the TurboSmooth and MeshSmooths modifier for the selected objects.
It is convenient to select all objects with the TurboSmooth or MeshSmooth modifier, then remove these modifiers for them. Through Add - add a new TurboSmooth modifier, so you can control the number of iterations on objects and get rid of the problem of "Isolated vertices" and incorrect Smooth Groups, after collapsing modifier stack.

Fit Model to Dimensions

stock model fixer tool tab fit model to dimension
Sets the size of the model along the specified axis.

Axis - the axis relative to which the size of the model will be set.
Fit Model - proportionally changes the scale of the model along the selected axis with the specified size in centimeters.

Set Pivot

stock model fixer tool tab set pivot
Allows you to quickly set the Pivot Point.

Bottom - sets the Pivot Point to the center at the bottom of the model. Suitable for most models that need to stand on a surface (ground).
Center- sets the Pivot Point to the center of the selected objects .
Top - sets the Pivot Point to the center of the top of the model. Suitable for hanging objects such as lamps.


stock model fixer tool tab position
Moves the selected objects to the center of the scene.

Set to Scene Center - move the selected objects to the center of the scene.


stock model fixer tab tools normals
Corrects the normals of the selected objects. A very useful feature for those who import objects from CAD programs, Sketchup, AutoCad, etc.

Specify - assigns Specify type to normals.

Reset - resets the normals to their initial state.

Attach Objects

stock model fixer tool tab attach objects
Attaches the selected models into one object.

Attach Selected - Attaches selected objects into one mesh. Thanks to special algorithms, this feature works faster than standard Attach tools in 3Ds Max.

Very often, models from stocks have many small objects combined into a group, or even worse, groups in groups, which has a very negative effect on the performance of the Viewport. By combining the selected models (Attach Selected) into logical pieces, for example a model with a sofa can be combined together, decor separately, lamps with cords and a stand are also separately, so you reduce the number of objects and unload virtual memory.
Convert objects to Mesh, this saves up to 30% virtual memory!

Renamer Tab

stock model fixer tab renamer 2
Helps to rename for the selected: textures, materials, objects, groups, layers.

To start renaming, enter Model Name. Do not be lazy to write the correct names.
Check the items that need to be renamed and click the Rename button.

If the option Move Model to Layer is enabled, the model will be moved to a separate layer. This is good if, for example, you need to create 100 chairs in the project scene, it will be much more convenient to work with a separate layer.
Renamer is useful when Cyrillic characters are used in names or incorrect names are used.

Check Tab
