reading textcoord from a multitextured mesh

HELLO GUYS


Ive been trying different ways to create a ray method that gives me back whatever texture is on a mesh by using the xna triangle picking sample as a starting point, but
theres just one last thing I need help with, implementing if statements that gives the string for each texture selected on a multitextured mesh. the modification info given I used are in the links below.THANKYOU

My project goal is to try to create certain sounds and particle effects based on the texture of the terrain the character is walking on
THANKYOU
