I'm just wondering if there is any possible way to trigger a BIK or AVI file during gameplay. I really wanted to create cutscenes in Source Filmmaker and then have them play on trigger touches.

Information on this subject seems to be somewhat sparse

There are some useful links in there, and NH2 creator gives some tips too.

Changing the code is much better than triggering the menu to pop up and then play the .bik.

Its not really that hard, add a point_clientcommand into your map and name it 'blah'. Then when the player walks into a trigger make the output: ontrigger, (the name of the point_clientcommand), command, playvideo <your.bikname>.
(Make sure your .bik file is in the media folder!!!)

I believe this only works in ep2 though as the other games dont have the playvideo cvar.

Good luck.
