Blotter.LiquidDistortMaterial is not a constructor

[heaversm]

Hi - just copying the example verbatim from the "basics/example2" documentation and getting an error:

Blotter.LiquidDistortMaterial is not a constructor at var material = new Blotter.LiquidDistortMaterial();

Any idea what's going on? My html just includes a script with the current production version of blotter, and then another script tag to the code that instantiates blotter, plus a valid dom element to insert the text into.

For anyone else who might have been initially confused following the official tutorial:

Make sure you are also create the file for whatever material you want to use. In case of the tutorial you need the liquidDistortMaterial.js which can be found in this folder in the repo.
