Hi Everyone, I have just uploaded to my website Mic's Car tutorial (Mic is a former 3DRADer, maker of the 4x4 race car game). This is an in-depth tutorial and shows how to make a car for 3DRAD from start to finish, it is a .wmv, runs for 7+ min. and 37mb in size.
This is the best car tutorial for 3DRAD hope it is of help. You will find at huntspace/3D (link below) then select freegames then tutorial
