AccuRender 4.0 Standard Libraries

In AccuRender 4.0, the standard materials and plant libraries are in

...Program Files\Common Files\McNeel Shared\AccuRender Libraries\Libraries

It is recommended that you not make modifications to these libraries, but rather save your new and modified materials in custom libraries that you create as new libraries and give special names to (like Boeing_Project.mlib). For the location of those new custom libraries, see Add_a_Library

The reason for not modifying the standard libraries is to be compatible with other users in your organization or your clients. If you modify a named material definition in a standard library, when you ship drawings that use that modified material to someone else with AccuRender, their rendering will use the standard material definition, rather than the modified definition, and your renderings won't match.

When you ship your drawing files to another person to render, send your custom libraries with the drawings, and tell that person where they need to put them.
