# sorry, by "rigged up a script", i really meant that.
# this is built to be copy&pasted directly into the python interpreter and run from there.
# you'll have to change the hardcoded paths.
# the textures are dumped as .vtf files, which can be opened with vtfedit. that is the only tool i'm familiar with that works with dxt5 compressed data.
