Verifying Installation 

Upon successful installation the following files should be present:

  • <3dsmax>/Ephere.Plugins.Lucid.dll
  • <3dsmax>/Ephere.Plugins.Lucid.FlexAdapterCuda.dll
  • <3dsmax>/Ephere.Plugins.Lucid.FlexAdapterD3D.dll
  • <3dsmax>/Ephere.Plugins.Autodesk.Max.Lucid.Authorizer.dll (in non-demo version only)
  • <3dsmax>/NvFlexDeviceRelease_x64.dll
  • <3dsmax>/NvFlexExtReleaseCUDA_x64.dll
  • <3dsmax>/NvFlexExtReleaseD3D_x64.dll
  • <3dsmax>/NvFlexReleaseCUDA_x64.dll
  • <3dsmax>/NvFlexReleaseD3D_x64.dll
  • <3dsmax>/plugins/Ephere.Plugins.Autodesk.Max.Lucid.dlo (this directory could be different if you changed it during setup process)
  • <3dsmax>/scripts/
  • <3dsmax>/UI_ln/Icons/Lucid*.bmp (a total of 12 icons)

If not all of these files are present please try to reinstall lucid with logging enabled, read below how.



When starting Lucid for the first time you will be presented with a dialog box containing a button to assign the license. Simply click this button and, if internet connection is successful, the license server will be automatically installed and started.

If you have a license server installed on another computer you can enter its IP address and press Connect.


License Server IP 

During authorization, if a license server is not detected on localhost computer, you will be asked to enter the IP of the license server to which to connect. This IP is stored in the following file for future reference:
  • On Windows: C:\Users\USERNAME\AppData\Local\Lucid3dsmaxLicenseServerIP.txt

You can change the directory where this file is stored by setting the LUCID3DSMAX_LICENSE_SERVER_IP_PATH environment variable to another directory.


Diagnosing Installation Problems 

If you run into problems during installation please help us diagnose and solve your problem by following these steps.

  1. Go to the directory where the install MSI file is located
  2. Open Windows command prompt using Windows Key -> "cmd"
  3. Type cd INSTALLER_DIRECTORY to go to the directory of your installer
  4. Use the following command to run the installer which generates a log file:
    start msiexec /i InstallerFileName.msi /l*v Install.log

    Note: Change the "InstallerFileName" to the name of Lucid's installer file
  5. After installation a file "Install.log" will be generated
  6. Please send it to us for analysis

Silent Installation 

Lucid uses MSI packages for deployment and installation.

Use the /quiet or /qn options with msiexec to perform a silent install.
  • Properties with name MAX_INSTALL_PATH_20XX can be used to specify the desired install locations for various 3dsmax versions.
  • Properties with name ENABLE_MAX_20XX can be used to disable installing Lucid for specific 3dsmax version. By default all 3dsmax versions present on the computer will be targeted, so one needs to exclude the versions not to target.

For example, this command installs Lucid for 3dsmax 2016 but not for 3dsmax 2014 with no UI and no reboot, with a log:

msiexec /i c:\path\to\ornatrix.setup.msi /quiet /qn /norestart /log c:\path\to\install.log MAX_INSTALL_PATH_2016="C:\Program Files\Autodesk\3ds Max 2016" ENABLE_MAX_2014=0
