la PLE n´est pas du tout complète et puis c´est pas celle de Maya 6 mais Maya 5 !
Voici les différences ( extrait du site) :
Maya Personal Learning Edition includes most of the functionality of Maya Complete with the following principle differences:
Performance
Maya Personal Learning Edition is limited to using a single CPU. The commercial version of Maya takes advantage of multiple CPUs, resulting in faster performance in areas such as software rendering, IPR and Paint Effects.
Watermark
A watermark text image appears across all rendered images and in some Maya Personal Learning Edition panels. The watermark does not appear when working in wireframe mode.
Rendering and Image Output
You cannot render using mental ray.
You cannot render using the vector renderer.
You cannot output 16-bit rendered image formats.

3D Paint Tool
Mac OS X: The command line rendering utility has been renamed from " Render" to " Render5PLE" to avoid conflict with the commercial version of Maya if it is also installed on the same machine.
