so i tryed the whole day to get it work but it doesn't. i made a car in 3ds max and used nadeoimporter to import to tm².
i can see and paint my car in the painter but can`t choose it in profile. i put the zip file in every directory thats possible( vehicles/carcommon ,vehicles/stadiumcar, models/carcommon ,models/stadiumcar). nothing worked for me.
i used the 3ds max file provided by bibigallaz and made some changes. exported as 3ds file and created the mainbodyveryhigh.solid.gbx. i also tryed to put the low poly model from bibigallaz as mainbodyhigh.solid.gbx and mainbody.solid.gbx into the zip file. also have the following files inside zip:

and ofcourse i bought the game.
maybe its a problem with my maniaplanet installation? i started with canyon beta and only installed the following updates till now. never made a fresh installation of the game! but had no problems till now.
if needed i can upload the 3ds max file or whatever is needed to proof.
please help!
