; Declare pixel shader version 1.1
ps.1.1

; Define t0 as a standard 3-vector from bumpmap
tex t0

; Perform EMBM to get a local normal bump reflection.
texbem t1, t0       ; compute new (u,v) values

#ifndef DO_WATER_ALPHA_TEXTURE

; result goes in output color multiplied by diffuse
mul r0, t1, v0

#else

;alternate version which uses a third texture which provides per-pixel alpha.
; result goes in output color multiplied by diffuse
tex t2	; get alpha texture
mul r0.rgb, t1, v0
+mul r0.a, t2, v0

#endif
