Assetto Corsa doen't allow some objects to be hidden (the AC_ someting objects) so the trick is to use a transparent override of their diffuse texture. Do you have kept the "transparent.dds" file in the extension folder ?Hi, fantastic extension as always.
To put a bit of a long story short, I've created another layout of Monza so that I can use this extension without it clashing with anything else (billboards etc), it uses the same .kn5s and models.ini as the original Monza layout but for whatever reason some of the brake markers dont disappear with the config installed (see pic). Is there anything I can do to fix this?
