it's fine.
there's a material file in each preset folder. you open the material file in notepad, in the preset folder your editing. say preset 3. you open Preset 3.material in Notepad. there should be both left body, right body, left head, right head, left eye, right eye, tail and mane. looking like this for each:
material preset_1_bodyMatL
{
technique
{
pass
{
texture_unit
{
texture preset_1body.jpg
you put the code I typed before, above 'texture unit'. and where it says 'Texture Preset_1body.jpg' you replace the jpg with png.
