I was wondering how you make invisible models for triggers.

I was wondering how you make invisible models for triggers.

First, flag the brush you want to use as a trigger as 'Empty', then, go to Face Attributes mode (select brush and press pagedown), check the box for transparency, and set the value to 1. 0 will not be accepted, but don't worry about the that. Click 'Apply'. You now have an invisible trigger brush the player can walk through, but will set off your trigger.
