I just did a completely new installation of my 3ds max 2017 and used the latest plugins that come in the rfactor 2 folder, but I receive the following error
change the library style from compact to the other mode, it happened to me without the gmt2 plugin , its a max bug
i have a question for you, maybe you know saw an old tutorial where in max scripts there was a gmt2 import option, do you have it or its an external script? as i unsterdand is, unfortunately, a script, hope i am wrong the script was linked in the tuto but the link is gone by ages.
