Foam in maya

[cily35]

QUESTION 1
i've import the foam texture genrated by HYBRIDO

i wanna use it in the shader of ocean mesh of simulation...

but i think is a question of UV, iv'è the problem with set the placement of tga foam seguence...
frist at all i mirror it (need like i see in yours tutorial) but when i play the simulation the tga foam doesen't merge with ocean mesh

i had belive to use tga foam like generate foam in ocean sheder of maya... or something like that
-------------------------------------------
QUESTION 2

i can't use RFRK.
i've import grid mesh and splash, foam particle...

when i render for exemple foam with grid mesh, i saw the particle go under grid mesh (cuz displacement i think, but i try unlees that and the result is the same), i've try a trick, i've modified "y" coordinate (+1/2) but i've erron in z,x can u help me?

thanks
Simone.
