assigning texture coord to prt loader

how can i assign texture coordinates to a prt loader?
they are all moving on the surface of an head, is there a way to pull it from the head or just create them from nothing?

im trying to apply the kcm with emission absorption and a texture map like in the tutorial to particles moving on a head, but without texture coordinates (which i have on a prt volume based off a sphere) i suppose it doesnt work

ok i got something, i used an input position channel, going To Space transform operator, feeding the texture coord output, gettin somewhere!
