reimplementing “Allow Wheel Rotation Against Engine” is quite easy if you’re building from source, you just need to add 2 lines to the wheel class, if you’re up to it drop a mail.
the origin of the wheel bone can be shifted on Y axis so I have added the rimoffset feature to quickly fix mismatches between physical wheel and the wheel mesh. it’s unlikely that the other axis’ will be shifted so the other offsets are not required and at the end of the day you can do that shift yourself in the anim bp.
