Material's broken.

Can’t see materials and can’t see fading doors but can walk through them.

I’ve tried -dxlevel but it seems like none of those are working for me. I can’t even start the game when I do -dxlevel. Not sure if I’m doing the wrong number for the -dxlevel though.

Add -dxlevel 95 to your command line options OR enter mat_dxlevel 95 into your console and restart the game, that should work too.

Didn’t work. Just tried doing the mat_dxlevel 95 then tested out the material in-game.

Do the -dxlevel then.
