There is something i don't understand, i followed these instructions --> http://supertuxkart.sourceforge.net/Ins ... he_tools_2
but i can't assign an object the wheel type in the property panel (i made this test with the cube you have when you start blender):


My question is: why ?
Thanks

Did you check Is a SuperTuxKart kart in the SuperTuxKart Scene Properties panel? (This is in the Scene tab of Blender's properties window.)

You're right ! I'm stupid ^^, thank you !
