Excerpt

Windows specific

1. "The material preview scene cannot be found."

Expand

This is related to the system environment variables. This error message shows up when you are trying to load Maxwell Studio without a layout. This happens because you had a previous version of Maxwell Render installed in another path and your MAXWELL3MAXWELL4_ROOT environment variable has not been changed correctly when you installed a new version. This means that the software is still referenced to the old path. It’s easy to resolve this issue. Revise the MAXWELL3MAXWELL4_ROOT environment variable and update the path, rewriting the new installation path in the corresponding window.

MAXWELL3

MAXWELL4_ROOT environment variable not found”

Expand

It has come to our attention that the installer is apparently having difficulty satisfying the prerequisite of finding MAXWELL3MAXWELL4_ROOT on some installations. The installer has always required this, but it seems that the Maxwell installer may be setting MAXWELL3MAXWELL4_ROOT only at the User level. So, if you get an error during the installation, indicating that Maxwell Render could not be found, or Maxwell Render doesn't start, please edit your machine's Environment variables, adding a System Environment variable called MAXWELL3MAXWELL4_ROOT, which points to your Maxwell Render directory, and another called MAXWELL3MAXWELL4_MATERIALS_DATABASE environment variable pointing to your material database folder (usually inside the Maxwell2 Maxwell 3 installation folder).

The two environment variables should be:

  • Name: MAXWELL3 MAXWELL4_ROOT Value: C:\Program Files\Next Limit\Maxwell 3 Studio 4 (or the location of your Maxwell install if different from this default one. If you installed Maxwell 32bit on a 64bit system, the install path would instead be C:\Program Files (x86)\Next Limit\Maxwell 3).

  • Name: MAXWELL3 MAXWELL4_MATERIALS_DATABASE Value: C:\Program Files\Next Limit\Maxwell 3Studio 4\materials database (or the location where you installed the Material Database, if different from this default location)

The System Environment variables are located in the lower box, as seen here:

1. I get the error that the RLM License Server is not running. How do I install it?

Expand
  • The RLM License Server installer is located in the disk image. Simply run it from there, no need to copy it. If you get an error message saying" RLM License Server cannot be opened because it is from unidentified developer", go to System preferences > Security to change the settings for running applications in your system, and allow Maxwell, or the RLM License Server in case you are installing the licensing server. After they have installed you can put the security settings to default.
  • Reboot your computer after RLM is installed.
  • Check that the RLM License Server has been installed and running by opening a browser window and typing localhost:5054. The RLM License Server interface should appear
  • Continue with the licensing procedure described here.
