L3Library is the core library we base our tools on. It provides Maya nodes, commands and scripted classes and functions. This lays the foundation for shared functionality and a framework for repititive tasks such as UI creation and automation.

You can download this library for free. It is provided "as is". A huge part of core classes and functions used to simplify Python scripting is still undocumented. At some point we may start to document internal library classes and functions and make them usable for your own tools.

We have been working with Maya since version 1.0. Supporting this software and sharing some of our technology with Maya’s community worldwide for free has always been very important for us. We spend the same enthusiasm to release robust, fast and production proven software when developing free tools, as we do for our commercial tools. This is a very time consuming process that has to be done in our spare time. Please use PayPal’s donate feature if you would like to support us. Thanks!

API Commands

• L3ClosestPoint
  Get closest point and UV coordinates on mesh, nurbs surface or nurbs curve

• L3Fingerprint
  Creates a software and hardware fingerprint used to license our tools

API Nodes

• L3AnimCurveWrapper
  Wrapper node that makes animation curves animatable. This node is a pure data container and has no functionality on its own.

• L3ArrayToColorSet
  Convert a data array to a color set. Currently only vector array data are supported.

• L3DecomposeMatrix
  Decompose matrix into individual translate, rotate, scale and shear values. Assemble new output matrix from seleted transformation components.

• L3GeoLocator
  Transform/geometry constraint with integrated dynamics, procedural animation features and wheel computation.

• L3ProjectionPlane
  Projects point onto plane and outputs intersection point and angle value.

• L3SpherePlacement
  Spherical locator node

• L3TimeToFrame
  Convert Maya’s time to a double value without time conversion

The library also includes bug fixes for known Maya limitations. To activate these bug fixes you must set environment variables in the Maya.env file.

• Timeline Update Fix
  When loading a scene file the time slider is not set to the current frame but stays at zero. To activate the bugfix add the following line to the Maya.env file:
  L3TimelineUpdateFix = 1
