When you contact support or log bugs, it’s nice to provide the version number and build ID of the MtoA version that you’re using.

This information is displayed in the Arnold > About box.

But the build id (circled in the screenshot) is kinda a pain to type out. Fortunately, you can get the build ID with the arnoldPlugins command:

arnoldPlugins -gbi;
// Result: 261bd4ca (master) //

You can get both the MtoA version and the MtoA build ID like this:

print( "MtoA " + `pluginInfo -v -q "mtoa.mll"` + " - " + `arnoldPlugins -gbi`);

In Python:

print( "MtoA {} - {}".format( cmds.pluginInfo( 'mtoa', query=True, version=True), cmds.arnoldPlugins(getBuildID=True) ) )
# MtoA 1.4.2.2 - 261bd4ca (master)
