is there a tool that creates the dx90 and dx80 vtx files?

im porting models from L4D2 to work in the EP2 engine, but it takes a long time to manually copy + rename the dx90 and dx80 files… is there a tool that does it for you?

Not that I know of, but it should be simple enough to write a script to do something like that.

If you just want to rename the files you can use http://www.bulkrenameutility.co.uk/Main_Intro.php. You’ll have to mess with it to get used to how it works.

Or you can download the VTX fixer. It is a .BAT file and will copy .VTXes for you.
