I have a less complex solution


it hase a couple more steps but they dont include code
and complex things and its the best way i know of
adding multiple textures to one figure other than
skin maping .. which is wayyyy more complex


1, open MED and load your ball

2, select the section of the ball you would like to cover
with the pic....

3, now open paint and open ur pic in it

4, save as... then in the save box the second dropdown menu that says
save as type: select : 24-bit Bitmap (*.bmp;*.dib)

5, go back to MED and select edit > manage skins > new skins, then check off the textures box then click texture file then click the button with the three periods (...) then select the image you saved from paint

now have fuN!
