Working with Materialize

I am trying to set up materialize. The problem I am having is setting the default values with SCSS. First of all, the following will break the build.

.dashboard-landing {
  /** fade in the timeline */
  .timeline {
    @include transition(.3 ease);

This will say that transition is not defined, when it should be.
Also, Materialize seems to say you should override their _variables.scss file in order to change the defaults, but that doesn’t work with scss. What do?

Hey! Are you using a materialize package?

yeah I am using the materialize:materialize package with fourseven:scss

If you have a look at the package.js for materialize you’ll see that it’s adding an already preprocessed version.
