Introduction to Blendshapes in Autodesk Maya: A Beginner's Guide

This lesson provides an introductory overview of Blendshapes in Autodesk Maya. A Blendshape allows you to morph one version of a model into another by changing the vertex positions, provided both versions share the same number of vertices. The process starts with duplicating a polygon model, adjusting its shape using the soft select tool, and finally creating the Blendshape within the Animation subset. This guide offers fundamental insights into enhancing character expressions through the Blendshape technique, paving the way for more advanced animation techniques.

  1. MAYA MONDAY LESSON 2014 B AIM: Introduction to “BLENDSHAPES”

  2. MAYA MONDAY LESSON 2014 B A Blendshape is exactly that. It will “blend” one version of a model to another. A Blendshape needs to have the same amount of VERTICIES in order to work.

  3. MAYA MONDAY LESSON 2014 B The basic way to get started with blend shapes is to go to EDIT/DUPLICATE in Autodesk Maya and make a couple of versions of a polygon model. Move it out of the way so it doesn’t take up the exact same space…

  4. MAYA MONDAY LESSON 2014 B

  5. MAYA MONDAY LESSON 2014 B If you look close at the previous slide, you will notice that the “expression” of Samantha’s bi-pedal was changed by moving the verticies. Also, I double clicked on the move tool and turned on soft select…

  6. MAYA MONDAY LESSON 2014 B By turning on “soft select”, the model (also called a “mesh”) verticies moved a bit more like skin might move on a bi-pedal. You can try blendshapes on any model.

  7. MAYA MONDAY LESSON 2014 B After you make several versions of your model, select them and make sure you are in the ANIMATION subset. Then you can go to CREATE DEFORMERS/BLENDSHAPE.

  8. MAYA MONDAY LESSON 2014 A Lastly, on the INPUT NODE in the Channel box, you will note a BLENDSHAPE option. Right clicking on that will allow you to KEY SELECTED as you move the numeric value from 0 to 1. (or another number)

  9. MAYA MONDAY LESSON 2014 A The next step from this lesson would be to make a connection between the Blendshape node and a Control Curve on a rigged character.
