Xgen is one of the most used groom tools for both professional artists and also students. But the comprehensive information about the usage of the expressions, which is one of the most important parts of the software and whats makes it so strong. So after the request from the Patrons on the channel, I decided to make this guide on how to use some of the most basic expressions that will give you more control over the groom.

The expressions for xgen are based on seexpr that was developed by the Disney. And xgen uses this language as part of his core for the different behaviors, noises and patterns. You can find more information on the RenderMan SeeXpr page and of course Autodesk help page with a guide for the available commands and possible usages. Some other useful links Intro to Xgen Expressions.

On this case we will use my personal library of expressions, developed trough trial and error and with the help of amazing artist and developers.
