Where did you get the remapped M4?

I would strongly suggest that you contact the creator of the remap for directions on how to undo it.

The only thing that I can think of is that you've created a character based on the remapped M4 and saved that. Deleting the original remap might not change this saved character.

As I understand it, usually a remap like this creates a second CR2 and maybe a second OBJ file; it should *not* overwrite your original files.

If you need to reinstall M4, download the M4 base from DAZ again (free) and install it. This will create a new (original) M4 OBJ and CR2 with the original mapping information. This should allow you to create M4 characters as long as you start from the new M4 figure.

I hope that this works.
