Learning Basic MEL Scripting
Autodesk is a company that creates 3D computer graphics programs. Their latest video series aimed at teaching beginners how to script in Maya will get you started with basic MEL scripting and cover three smaller projects over the course of three tutorial videos!
The first video tutorial demonstrates how to create a script for the Maya shelf that can help you with instances of objects in selected vertices. In addition, this same concept is expanded upon by another viedo demonstrating per-face instancing; placing models on specific faces rather than their centers will allow designers greater control over where each instance lies within space .
The third installment of the tutorial offers a look at how to create custom controllers using NURBS curves, so that assets can be posed and placed easily.
