Understanding the new Licensing check interval

Posted on by
Reply

As of the 2013 release, you can now set up your license server and Softimage workstations so that idle licenses are reclaimed by the license server and distributed to other machines.

An instance of Softimage (xsi.exe) is considered idle when there is no mouse or keyboard interaction, no command or script running, and no active progress bar. Softimage is never idle in batch mode.

2013 includes a new Licensing check interval preference (Preferences > General). Basically, this “check interval” is how long Softimage can be idle before it will give up its license. By default, the Licensing check interval is 1 minute. That means that if Softimage is idle for a minute, then the license server could reclaim the license and give it to some other user. To disable the license time-out feature, set the check interval preference to 0.

By default, the license server does not reclaim licenses when Softimage is idle. To configure the license server to reclaim idle licenses, you need to set the TIMEOUT option. To do that, create a plain text file named adskflex.opt in the same folder where your license file is located.

To set the TIMEOUT to 60 minutes for an Entertainment Creation Suite Ultimate license:

TIMEOUT 85926ENCSU_2013_0F 36000

To set the TIMEOUT for a 2012 Softimage license:

TIMEOUT 85705SFTIM_2012_0F 36000

You will need to restart the server to read the changes to the options file.

With the TIMEOUT option set on the license server, the next time your Softimage is idle for longer than the check interval, the license server may reclaim the license to give to another user. When you start working actively with Softimage again, it will try to check out another license from the server. If it gets a license, you’ll keep working and you’ll never know your license had been “lost” while idle.

However, if no licenses are available, you’ll see this:

and then you’ll have a chance to save your work:

#include statement in JScript

Posted on by

JScript doesn’t include anything like the #include statement, or like modules in Python.

But what you can do is read the contents of a file into a string, and then eval() the string. For example:

var fso = ActiveXObject("Scripting.FileSystemObject");
var f = fso.OpenTextFile( "//server/scripts/toinclude.js", ForReading );
var s = f.ReadAll();
eval(s);
s.Close();

Note that if there’s any errors in the included code, you won’t get the right line numbers in the error messages.

In JScript, another approach would be to create a custom object that has all the helper functions as methods. For an example of that kind of thing, check out the WizardHelperObj object in

%XSI_HOME%\Addons\sdkui\Application\Plugins\SDKWizards.js

Then you just provide one custom command that returns an instance of the custom object to whatever code needs to use the helper functions.

The case where there was no way to disable Face Robot

Posted on by

I’ve seen a few cases where a user couldn’t disable Face Robot, because there was no Face Robot module or menu.

That’s because the module menus were hidden. To show the module menus, right click and empty area on the Softimage menu bar, and click Module Menus.\

Then you can click Face Robot > Disable Face Robot.

Copying tangent data in a crowd

Here’s a video walkthrough that shows how to get tangent data on the source actor and copy it to the actor copies. It’s basically a two-step process: first, copy the tangent data to a custom attribute on the mesh proxy, and the copy the attribute from the proxy to the actor copies. That’s basically what CrowdFX does for you for the default Texture_Projection.

I did this video for a customer who wanted the tangent data for the normal maps on the actor copies.

Copying tangent data with ICE modeling

Here’s an example of using Copy PolyNode Data from Source to copy tangent data from a source mesh to a cloned mesh. Typically you would plug this into the Execute on Copy port of a Create Copies from Polygon Mesh or Clone Polygon Mesh, but here I’ve done something more basic.

To display the tangent data of the clone in the viewport, I’m using the Vertex Color Display Property setting (OpenGL Display tab of the material applied to the clone).

More on getting the version of Softimage used to create a scene

Whenever you open a scene, you’ll see a message like this logged to the script history:

# INFO : 4034 - Loaded scene was created with build number: 10.5.98.0 - compatibility version: 1000
Application.OpenScene("C:\\Users\\blairs\\MyProject\\Scenes\\2012SAP_Scene.scn", "", "")

# INFO : 4034 - Loaded scene was created with build number: 10.1.62.0 - compatibility version: 1000
Application.OpenScene("C:\\Users\\blairs\\MyProject\\Scenes\\2012SP1_Scene.scn", "", "")

If you want to know the version of Softimage that was used to create the scene, you need to check the specific build number (and there’s a couple of ways to do that, we’ll get to that in a second…).

The compatibility version is more a property of Softimage itself than of the scene. You can get the value of the project.CompatibilityVersion parameter, but it’s always going to be the compatibilty version of the current Softimage instance, not of the loaded scene.

p = Application.Dictionary.GetObject( "project.CompatibilityVersion" )
print Application.ClassName(p)
print p.Value

# OR

print Application.GetValue( "project.CompatibilityVersion" )

To find out the version of Softimage used to “build” a scene, you can use the printver utility, or look in the scntoc file. In this context, “build” means the version of Softimage that was last used to save the scene. I note that just opening a scene and saving it isn’t enough to bump up the build version. You need to do something to the scene, or at least do something and then undo it.

From Jeremie Passerin on the Softimage mailing list, here’s a Python snippet that reads the version from the scntoc:

# Python Code
import xml.etree.ElementTree as etree

ext = 'scntoc'
scn = 'C:\\Users\\blairs\\Project\\Scenes\\Test.%s' % ext

tree = etree.parse( scn )
root = tree.getroot()
version = root.get("xsi_version")

LogMessage(version)

Here’s a JScript snippet that reads the version from the scntoc:

var dom = new ActiveXObject("msxml2.DOMDocument.6.0");
dom.async = false;
dom.resolveExternals = false;

ext = 'scntoc';
scntoc = 'C:\\Users\\blairs\\Project\\Scenes\\Test.' + ext;

dom.load( scntoc );
var oNode = dom.selectSingleNode("xsi_file");
LogMessage( oNode.getAttribute( "xsi_version" ) );

If you don’t want to rely on the existence of a scntoc, you could use the printver.exe utility that ships with Softimage. Given a scene file, printver prints a message that looks like “This Scene was built with version: 11.0.525.0”.

Here’s a JScript snippet that runs printver and gets the version number from STDOUT:

// JScript
var WshShell = new ActiveXObject("WScript.Shell");

scn = "\\\\server\\Project\\Scenes\\Whatever.scn"

sExec = "printver " + scn

var oExec    = WshShell.Exec( sExec );

while ( !oExec.StdOut.AtEndOfStream )
{
	s = oExec.StdOut.ReadLine();
	if ( s.indexOf("This Scene was built with version") != -1 )
	{
		var version = s.split(":")[1].replace(/^\s\s*/, '').replace(/\s\s*$/, '');
	}
}

LogMessage( version )

And here’s a Python snippet:

import subprocess

scn = 'C:\\Users\\blairs\\Documents\\Support\\Project\\Scenes\\MySphere.scn'
p = subprocess.Popen( 'printver -l %s' % scn, stdout=subprocess.PIPE )
stdout = p.stdout.readlines()
print stdout
print stdout[-1].split(':')[1].lstrip().rstrip()

See the thread on the Softimage mailing list, which includes a VBScript snippet for getting the build version.
