Frequently Asked Questions

[ Also see the GPU FAQ ]

Systems / Settings

How Do I See My Environment Variables?

To see what environment variables are enabled, select :

  • My Computer (Right-Click) / Properties
  • Advanced system settings (on left)
  • Environment Variables button

A list of environment variables for your current user is shown on top, and system variables below. A Digital Vision environment variable (e.g. NUCODA_ROOT_V2014_2) will be set in the system set.

How to Extend the PATH Environment

Extending the Windows PATH environment allows you to type a command without needing to specify the command's full path i.e. run :


Rather than :

C:\Program Files\Nucoda\2014_2\nucoda.exe

Windows will search the environment (folders) specified in the PATH variable to find commands. To extend the PATH :

  • My Computer (Right-Click) / Properties
  • Advanced system settings (on left)
  • Environment Variables button :
  • In the System variables (bottom), find the Path variable and select it :
  • Press the Edit button
  • At the end of the value line :
    • Add a semi-colon, then the folder to add e.g.
      ;C:\Program Files\Nucoda\2014_2\

  • Press OK

You will need to restart any programs (including CMD shells) for the change to be seen. In a CMD shell, check the setting via :

  • echo %PATH%

How to Determine the Number of CPU Cores?

On Windows 7, you can determine how many CPU cores you have by following these steps :

  • My Computer (Right-Click) / Properties
  • Select : Device Manager
  • Open the Processors group
  • Count how many processors are listed.
  • Use this number for the renderFrameThreads preference setting.


Where is my ROOT Folder?

The ROOT folder is the location of the application's main preference folders and configuration.

It is defined in the environment variable :


where :

  • XXXX_X is the version as MAJOR_MINOR e.g. 2013_3

By default, the ROOT folder is a folder like :

Control Panels

How Can I Change the Sensitivity of Controls on the Tangent Element?

Use the Tangent Element Mapper software to adjust the Element control sensitivity.

  1. Select the tool to change at the top (e.g. Balance)
  2. Select the panel to target (e.g. Element-Tk)
  3. Change the sensitivity as desired.

On exit, you will be prompted to save a new profile.

Note, from the Tangent Element Guide :

Sensitivity can be set in the Tangent mapper application. When making the setting, be sure to use the mouse pointer to click on the arrow head and drag it to the new position on the sensitivity scale, else it will not register the change. This seems to be a bug in the mapping software.


Clean Install

A clean installation ensures we use the installer versions of all settings and preference files.

A standard installation of the same major version of the application (Nucoda or Phoenix) will be placed in the same folders as any previous installation.

For instance, installations of release 2018.1 will be placed inside a 2018_1 folder e.g. for Nucoda :

C:\Program Files\Nucoda\2018.1

A standard installation will not overwrite settings and preference files within this folder.

Occasionally, a release includes updated configuration or preference files that should be installed over existing versions. However, we cannot simply overwrite them because the local copies might have been modified by the user (and we would therefore lose these changes). In circumstances like this, we recommend a clean install.

A clean install will ensure all updated files and settings are installed. To do this, you should move the original installation folders out of the way before installation of the new version.

This just involves renaming the top level "versioned" folders. For example :

For Nucoda :

From :
C:\Program Files\Nucoda\2018.1
To :
C:\Program Files\Nucoda\2018.1.BAK

For Phoenix :

From :
C:\Program Files\Phoenix\2018.1
To :
C:\Program Files\Phoenix\2018.1.BAK

After renaming these folders and running/re-running the installer, you will have all the new updated settings installed.

You will now also need to :

  • Copy (or move) your original projects into place and re-attach them
  • Copy any changes you made in the previous preference files to the new ones
