MayaStation posts a quick little tip on finding out how much memory is being used on a scene in Atudodesk Maya with a simple MEL command. – How handy is that!?
“Ever wondered how much memory your file consumes? Use the following MEL while working on your file
memory -sum;
you can use other flags such as -fm
memory -sum;
memory -freeMemory;
For more information please refer to the documentation under the MEL section.”
