Portal 1 in Portal 2 DLC Progress Update

playthrough of portal 1 showing the different issues and tricks you can/like to do.
maybe the chamber 11 door could be deleted after it opens but before it closes to reduce jarringness
currently it's in override mode, needs vscript and separate models/materials to avoid conflicts with portal 2.
elevator transition bug does not happen in certain portal 2 builds particularly older than october 2015
