Indigo Manual > Getting Started

Installing Indigo

To download Indigo, go to and select the appropriate version of Indigo for your platform (Windows, Macintosh or Linux). You should download the latest available version of Indigo, which will be listed at the top of the page.

System Requirements

Indigo will run on most modern computers (generally Pentium 4 or newer).

Please see the final section for GPU acceleration requirements and suggestions.

Minimum system specifications:
  • 64-bit x86 CPU with SSE4
  • 4GB of RAM
  • 150MB of hard drive space
  • Windows 7 or newer
  • 64-bit x86 CPU with SSE4
  • 4GB of RAM
  • 150MB of hard drive space
  • OS X 10.8 Mountain Lion or newer
  • 64-bit x86 CPU with SSE4
  • 4GB of RAM
  • 150MB of hard drive space
Recommended system specifications:
  • 16GB+ of RAM
GPU acceleration
  • Either an NVIDIA GPU supporting OpenCL 1.1 (GeForce 9800 GT or newer), or an AMD GPU supporting OpenCL 1.1 (Radeon 4xxx or newer)
  • 256MB or 512MB of onboard GPU memory, depending on OS (more info)
  • 2GB of system memory
  • Either NVIDIA GeForce GTX 5xx / Quadro 4000 / Tesla C2050 or newer, or AMD Radeon 5xxx / FirePro 3D V3800 / FireStream 9350 or newer
  • Quad-core or greater Intel or AMD CPU
GPU memory requirements

We recommend 512MB instead of 256MB as the minimum on Mac OS and Windows Vista/7 using the Aero desktop, since it uses more GPU memory for desktop window management.

If you are using an older GPU with relatively modest specifications, we encourage you to try the trial version before purchasing.

Indigo for Windows

Downloading and installing

Download the newest version of Indigo for Windows, then double click the installer file.

  1. Agree to the licence

    You will be presented with the Indigo End User Licence Agreement. You should read through it and click "I Agree" if you agree with the terms.

  2. Choose components

    We recommend you leave the check-boxes selected but you are able to disable each component if you have particular requirements on your system. Press Next to continue.

  3. Choose an installation location

    We recommend you use the default installation location, as most Indigo exporters will expect to find Indigo here – however you are able to change this path if you need to. Indigo will write a registry key that exporters will use to find Indigo automatically if Indigo is installed in a non-standard location. Press "Install" to complete the installation.

After installation

Once the installation has completed, you can find Indigo from the start menu under the "Indigo Renderer" or "Indigo RT" sub-menu, along with links to this manual and other program shortcuts for convenience.

Indigo for Macintosh

  1. Download the newest version of Indigo for Macintosh then double click the disk image mount it.
  2. A dialog will pop up, prompting you to drag the Indigo icon to your Applications directory:

  3. Drag the Indigo icon to the Applications directory.
  4. Indigo is now ready to be used on your Mac.

Indigo for Linux

  1. Download the latest Indigo for Linux from
  2. Extract the archive that you downloaded, for example with the command:
    tar -xzvf IndigoRenderer_x64_v3.4.18.tar.gz

    This will extract the archive into the directory dist/IndigoRenderer_x64_v3.4.18

  3. Indigo is statically linked as far as possible and should be ready for use. Run ./indigoconsole -v to see if Indigo installed correctly, for example:
    cd IndigoRenderer_x64_v3.4.18/
    ./indigo_console -v

    Which should print out something like

    Indigo Renderer v3.4.18, Linux 64-bit build.

    To run the graphical user interface, run ./indigo.

You are now ready to run Indigo.

Indigo Licensing

You are welcome to learn Indigo and use it for non-commercial renders without paying for a licence. The following restrictions are present in the free version of Indigo:

  • Maximum resolution of 1.0 Megapixels – e.g. 1000 pixels by 1000 pixels.
  • An Indigo logo is placed in the bottom right of the image.
  • May not be used for commercial work.
  • No customer support beyond that given in the Forum.

If you need to create renders at higher resolutions or produce renders as part of your business, then you need to buy a commercial licence for Indigo. You can buy licences online at:

Once you have purchased a licence, you can instantly enable the full features of Indigo. Your licence will be locked to the hardware of your computer, and you must contact if you need to move the licence to another computer.

The licence for your computer is based on the CPU model of your processor and MAC address of your network card. You should avoid changing your network card regularly when using Indigo – for example avoid enabling and disabling your network card, as this may confuse the licensing software that Indigo uses.

If you wish to purchase multiple licences, you can use the network floating licence feature, managed by the Network Manager. To purchase these licences please contact us at

There are two different kinds of Indigo licences:

  • GUI Licence – for use on your desktop computer
  • Node Licence – for use on networked render slaves

Having a GUI Licence does not mean that you can use unlicensed render slaves to generate a high resolution image, you will need a node licence for each computer that will be used to help you render your image.

If you have any problem with your Indigo licence, you can always contact us at and we'll get you up and running as soon as possible!

Indigo Licence Activation

Once you have purchased an Indigo Licence from the Glare Technologies Store you need to go through a few steps to activate it with Indigo.

  1. Open Indigo and click on the Licensing button.
  2. Press Copy to Clipboard to copy the hardware key. Do not copy the text manually.
  3. Upon purchase of a licence, you will receive an email with a link to the store page with your details on it. Keep this link somewhere secure, and check that your details are correct.
  4. Scroll down to the bottom section. Paste in your hardware key into the appropriate box, depending on the type of licence you own, and press "Generate Licence Key".
  5. A bunch of characters will be returned in a text box, copy it all.
  6. Paste it back into the Indigo Licence dialog box at the bottom, and press "Verify licence key".

  7. Success!

  8. The Indigo background will also tell you if it is verified.
Floating Licence Activation
Getting the server Hardware ID

First, decide which computer you will use as a licence server.

Install Indigo Renderer (which can be downloaded from on your server.

Run the "Indigo Network Manager" on the server.
(For example, on Windows, this can be accessed Start -> All Programs -> Indigo Renderer -> Indigo Network Manager)

Press the Licensing button, then "Copy to Clipboard" to copy the hardware ID for the server.

Email the hardware ID to
If you have purchased floating licences, we will reply with the licence file based on the hardware ID and the number of licences purchased.

Using the Licence Key

Once you have received your licence key by email, open up the Licensing dialog in the Indigo Network Manager again. Then paste the licence key into the text field labelled "Enter your licence key".

Finally, press "Verify licence key" and of the licence key is valid, the "licence status" field will display a message similar to the following:

Licensed to 'Nick Chapman'
Email: ''
5 x Network Floating Full

If the licence key is not valid, an error message will be displayed instead in the licence status field; please contact for assistance.

Using the Floating Licences
Obtain the Licence server's hostname

A hostname is a name used to identify a device connected to a computer network.

See the Network Rendering tutorial, step 3, for more information on this.

Make sure the Indigo Network Manager is running on the licence server, and the licence key is loaded into it as described earlier.
Set up Indigo on your workstation(s)

On your workstation computers, install Indigo Renderer.

Start Indigo Renderer.

  1. Click on the "Options" tool-bar button.
  2. Select the "Network" tab in the options dialog.
  3. Ensure that the "Use network manager" option is checked.
  4. In the "Network manager hostname" field, enter the licence server hostname.
  5. Ensure that the "Use floating licence" option is checked.
  6. Ensure that the "Do master search broadcast" option is unchecked.
  7. Click "OK" to save the changes and exit the options dialog.
Test retrieval of the floating licence

Restart Indigo on your workstation.

When Indigo starts, the Indigo logo and some information will be displayed in the main window.

If the floating licence retrieval was successful, the Licence type will be 'Network Floating Full' and
the Licensed to will be 'Network Floating Licence User', as shown:

Network ports

Some ports will need to be opened on the licence server, so that Indigo running on the workstations can connect to it: TCP Port 7200.

Network manager logging

The Indigo Network manager writes out reasonable comprehensive logs to network_manager_log.txt in the appdata directory, for example C:\Users\nick\AppData\Roaming\Indigo Renderer\network_manager_log.txt.

Looking at this log can give useful information if floating licences are not working.
