Installing on Linux

After installation, Modo is run from either desktop icons, the browser, or from the Terminal using arguments.

Modo System Requirements

Qualified Operating Systems

Red Hat Enterprise Linux 5.4 or greater

Note:  Other operating systems may work with Modo, but have not been fully tested. If you have any problems with a particular system, please contact our support team.

Other System Requirements

Intel Xeon/Core 2 Duo, Quad/Core i7 or AMD Opteron/Phenom processor(s). Must support SSE2 instruction set.

• 1 GB available hard disk space (for Modo installation).

• 6 GB available hard disk space (for full content).

Core set of content: Basic sets of assemblies, aliases, brushes, colors, Matcaps, basic and sculpting meshes, profiles, paint and sculpt tools, and image links are provided with the application install. The Preset Browsers now virtually merge these built-in presets with those installed externally or saved/created by the user into a single hierarchy for ease of use.

2 GB of system RAM.

Accelerated Video Graphics adapter with OpenGL support capable of minimum 1280 x 800 resolution.

Mouse or compatible pointing device (pressure sensitive tablets supported or 3DCONNEXION 3D mouse).

Internet connection required for product activation and access to online videos.

Current web browser application necessary to view the Online Help.

Tip:  Many machines (especially laptops) include what is called an 'integrated graphics adapter', the necessary component in a computer to display images on your screen. These machines, while economical, often share memory with the CPU and are designed more for power saving than for performance, with their drivers often barely, or very poorly, supporting standards necessary to Modo.

Many issues in Modo can be traced to the graphics adapters and their drivers. The Foundry highly recommends the use of a discreet graphics adapter (often branded by AMD or Nvidia) for the best overall user experience.

Installing Modo on Linux

To install Modo on Linux, see either:

Installing Modo from the Terminal, or

Installing on Linux.

Installing Modo from the Terminal

To install Modo from the Terminal, do the following:

1.   Download the correct .run installation file from our website at

The .run file is saved to your preferred download location.

2.   Open the Terminal.
3.   Use the cd (change directory) command to move to the directory where you saved the installation file. For example, if you saved the installation file in /home/user1/Downloads, use the following command and press Return:

cd /home/user1/Downloads

4.   Run the installer.


5.   Follow the on-screen instructions. By default, Modo is installed to the directory to which you saved the installer.
6.   If you didn’t add a license key during the installation, do that now. Proceed to .

Note:   By installing Modo silently, you agree to the terms of the End User Licensing Agreement. To see this agreement, please refer to END USER LICENSE AGREEMENT (EULA) or run the installer in standard, non-silent mode.

Launching Modo on Linux

To launch Modo on Linux, do one of the following:

Open the Modo application directory where you installed Modo, and double-click the Modo icon.

Using the Terminal, navigate to the Modo application directory where you installed Modo, and enter:

./Modo12.0v1 to launch Modo.

If you already have a valid license, the graphical interface appears. If you don't have a license, or haven't installed one yet, the Licensing dialog appears on start up.

For more information on how to license Modo, refer to Licensing Modo on Linux.

Running in Slave Mode

Slave mode is related to network rendering and places Modo in a state where other Modo installations can control its renderer. For information on how to set up Network Rendering, please reference the Network Rendering page.

Running in Play Mode

Play mode places Modo in a special state where it acts as a scene viewer. In this state the interfaces are mostly disabled, but it allows you to load scenes and render and save them, both in Preview and using F9; opening the Render Display window.

One unique function of Play mode is its ability to detect scene changes and auto-reload the scene. What this means is any scene opened from over a network and previewed, when updated on another system, saves files to the scene file, reloads the scene on the networked system and updates the preview viewport. This allows the secondary system to act as a dedicated preview system without the need for a second license.

Manage Licenses

Clicking this button opens, where you can manage your subscriptions.


By pressing the Status button, information is collected to assist our Support team to debug your license problem. This report contains the System IDs and more information that they need to assist you. There are a number of ways to submit this information. For more information, see Installing on Linux.

Proxy Server

Specify an optional proxy server and port for accessing the internet from behind a firewall.

Updates and Statistics

When Modo launches for the first time, you are presented with a dialog, which enables you to set preferences to check for updates and to submit usage statistics.


Get the latest reminders to update Modo. You can have Modo automatically check for updates on every launch, daily or weekly. By default, this preference is set to Never.

Usage Statistics

To help improve the quality of Modo, you can agree to submit usage data to the Modo Development team. These statistics are submitted anonymously and include details on the build number run, the system platform, the application active and idle times, and whether sessions exit successfully or not. In the event of a crash, the most recently executed commands are also submitted.

Note:  Graphics card information is not submitted.

Tip:  To reset your settings, open System > Preferences, expand Defaults > Application and reset the options for the following:
Automatically Check for Updates
Automatically Submit Usage Statistics

The following settings are available: Never, Every Launch, Daily, or Weekly.

Running in Safe Mode

In the unlikely event of a crash, you can run Modo in Safe Mode to help us determine what is causing the problem. When Modo runs in Safe Mode, it doesn't load any third-party plug-ins, kits, or user customizations and only runs using the contents of the Modo install directory. Safe Mode is primarily used for debugging purposes. When running in Safe Mode, a pristine configuration file is used.

Note:  When exiting Safe Mode, your existing configuration file (modo_12.0v1.rc) is not overwritten.

A backup of configuration file is created at shutdown, when changes are saved. This backup file can be renamed to restore the previous state if configuration changes cause issues. When a corrupt configuration is detected, it is renamed, instead of deleted, which allows you to recover data from corrupted configuration file.

Save your configuration file and submit it to Support for debugging. Your configuration file is stored in the /home/<username>/.luxology directory.

To run in Safe Mode:

Using the Terminal, navigate to the Modo application directory where you installed Modo, and enter:

./Modo10.2v2​ ​-safemode -dbon:noconfig​​

If Modo successfully launches in Safe Mode, click File > Config Save to overwrite your existing configuration file that was causing Modo to crash.

Licensing Modo on Linux

The following licensing methods are available:

Subscription Licenses - subscription licensing differs from traditional node locked or floating licenses in that a single license, or subscription, is valid on any activated device up to the subscription's maximum number of activations.

Activation Keys - activation keys allow you to activate and generate your actual product license key, at a later point after purchase, on the machine for which you require the license. They are provided for both node locked and floating license, and generate the appropriate license type once installed using the product's Licensing dialog or online using the Activate a Product page:

Node Locked Licenses - these can be used to license an application on a single machine. They do not work on different machines and if you need them to, you’ll have to transfer your license.

Node locked licenses, sometimes called uncounted licenses, do not require additional licensing software to be installed.

Floating Licenses - also known as counted licenses, enable applications to work on any networked client machine. The floating license is put on the server and is locked to a unique number on that server.

Floating licenses on a server requires additional software to be installed on the server to manage the licenses and give them out to the client stations that want them. This software is called Foundry Licensing Tools (FLT) and can be downloaded at no extra cost from our website.

These instructions run through the basic options for both licensing methods, but you can find a more detailed description in the Foundry Licensing Tools (FLT) User Guide available on our website:

Note:  If you are simply installing render nodes on a networked system, no license is required for Modo. Modo can also be run in Play mode to load scenes, navigate the viewport to look at them, and to render them (stills or animations). This allows you to render scenes on one system while continuing to work on another using your license. Play mode is available in the licensing dialog, by clicking Advanced > Run in Play Mode. For more information, see .

In all other instances, you need to have a license or a trial version of Modo.

To Install a Subscription License

Subscription licensing differs from traditional node locked or floating licenses in that a single license, or subscription, is valid on any activated device up to the subscription's maximum number of activations.

• A Subscription represents the right to run a Foundry product for a set amount of time on a set number of devices.

• An Activated Device is a recognized device, such as a desktop computer, on which subscriptions can be activated.

For example, if a subscription for Modo has five activations, you can use Modo on five separate devices simultaneously. If you want to activate another device, you have to deactivate an existing one, but you can activate and deactivate devices as often as you like.

Subscription licenses require that you connect to the internet at least every 30 days to extend your activation.

To activate your subscription license, follow these steps:

1.   Create a Foundry account using a valid email address on our website.
2.   Launch Modo using any of the methods described in Launching Modo on Linux.

The Licensing dialog displays.

3.   Enter your account email address and password and click Log In.
4.   Click one of the available licenses to activate.

A subscription license is created in your home directory: /home/<username>/FoundryLicensing/<SystemID>

Note:  Replace <username> and <SystemID> with the current user and the MAC address of the device, respectively.

The license looks something like this: c58edf7e-17ab-435b-8d8a-b3a9b347ab11.lic

5.   Once the license is installed, click Run MODO to start using Modo.

Note:  A license is activated for a period of 30 days. Make sure that you connect to the internet at least 30 days to extend your activation period. You can check the activation period of your license in the Help > Modo Licensing menu.

6.   If you need to deactivate your license on the current machine, navigate to Help > Modo Licensing, and click Log Out.

Obtaining Legacy Licenses

To obtain a license, you'll need your machine's System ID (sometimes called Host ID or rlmhostid). Just so you know what a System ID number looks like, here’s an example: 000ea641d7a1.

Bear in mind that, for floating licenses, you'll need the System ID of the license server, not the machines on which you intend to run the application. There are a number of ways you can find out your machine's System ID:

Launch the application without a license, click Status in the Licensing dialog, and then scroll down the error report until you see your System ID.

Download the Foundry License Utility (FLU) from and run

./FoundryLicenseUtility -i

Your System ID is displayed.

Download the Foundry Licensing Tools (FLT) free of charge from and then run /usr/local/foundry/LicensingTools<version>/Foundry LicenceUtility.

When you know your System ID, you can request a license for Foundry products:

from Foundry's Sales Department at

from the product pages on our website, such as

by launching the application without a license and selecting:

Buy Modo - opens a web browser directly to the Foundry website to purchase a license.

To Install a License from Disk

If you've installed a license to a known location on disk:

1.   Launch Modo using any of the methods described inLaunching Modo on Linux .

The Licensing dialog displays.

2.   Click Install Legacy License to display the available license installation options: Download Purchased License, Install Downloaded License from Disk, and Use Server.

3.   Click Install Downloaded License from Disk.
4.   Browse to the location of the license file.
5.   Click Open to install the license automatically in the correct directory.

Once the license is validated, Modo displays a notification dialog.


If you haven't already installed a license to a known location on disk:

1.   Launch Modo using any of the methods described in Launching Modo on Linux.

The Licensing dialog displays.

2.   Click Install Legacy License to display the available license installation options: Download Purchased License, Install Downloaded License from Disk, and Use Server.
3.   Click Download Purchased License.

The Foundry website's My Products page opens in your browser, and you can download the required license.

The license is installed to a specified location on disk.

To Install a Floating License

If you requested a floating license from Foundry, you receive your license key (foundry.lic) in an e-mail or internet download. You should also receive the Foundry License Utility (FLU) application to help you install the license key on the license server machine. The server manages licenses for the client machines on your network.

Note:   The FLU is also available to download from

To set up a license server:

1.   Make sure you have saved both the license key (foundry.lic) and the FLU application in the same directory.
2.   Run the FLU application.

The license key automatically appears in the FLU window if the FLU and foundry.lic are in the same directory.

Tip:  If they are not in the same directory, you can either copy and paste the contents of the license key or drag-and-drop the file into the FLU window.

3.   Click Install.

This checks the license file and, provided that the license is valid, installs it into the correct directory.

4.   In order for the floating license to work, you need to install the Foundry Licensing Tools (FLT) on the license server machine.

For more information on how to install floating licenses, refer to the FLT User Guide, which you can download from our website

To activate a floating license:

1.   Once your license server is up and running, launch the application on the client machine.

The Licensing dialog displays.

2.   Click Install License to display the available install methods.
3.   Click Use Server and enter the server address in the field provided. The format for the server name is: <port>@<servername>, for example, 30001@red.

Note:   You must perform these steps on each client machine that requires a license from the server.
