;------------------------------------------------------------------------------
; Draw a texture . . woo hoo!
; t0 - texture
;
; The texture coordinates need to be defined as follows:
; tc0 - texcoords
; c2 - envmaptint 
;------------------------------------------------------------------------------

tex t1	; cube map
tex t2	; envmap mask
tex t3	; detail texture

; version 1: applies the mod2x *after* environment map
; version 2 doesn't make sense here!
mul r0, t1, t2
mul r0.rgb, c2, r0
mul r0, r0, v0
mul_x2 r0.rgb, r0, t3	; mod2x detail texture
