Warning! This utility might damage your shaders! Details: Oblivion shaders always contain CTAB (Constant TABles) which are used by the engine. If you disassemble and re-assemble the shader's code then resulting shader differs from the original. As a result some variables might be unbound resulting in ex. missing water animation or other similar problems.

Editing the Night-Eye Shader

Original Shader

	ps_1_3
	def c0, 1, 0, 0, -1
	def c2, 1, 1, 1, 0.5
	def c3, 0.209999993, 0.5, 0.779999971, 0
	def c4, 0, 0, 0, 1
	tex t0
	dp3 r1, c0, c1
	add t0.w, c0.w, r1.w
	mul t0.w, t0.w, t0.w
 + dp3 r1.xyz, c2, t0
	mad r0.w, -t0.w, c2.w, c2.w
	cnd t0.w, r0.w, c3.w, c4.w
 + mul r1.xyz, r1, c3
	lrp r0.xyz, t0.w, r1, t0
 + mov r0.w, c4.w

// approximately 7 instruction slots used (1 texture, 6 arithmetic)

Very Bright

 ps_1_3
	tex t0
	mov_x2_sat r0, t0

// approximately 2 instruction slots used (1 texture, 1 arithmetic)

Super Bright Shader

	ps_1_3
	tex t0
	mov_x4_sat r0, t0

// approximately 2 instruction slots used (1 texture, 1 arithmetic)

Desaturated

   ps_1_3
	def c0, 0.300000012, 0.589999974, 0.109999999, 1
	tex t0
	mov_x2_sat r1, t0
	dp3_x2_sat r0, t0, c0
	lrp r0.xyz, r0, r1, r0
  + mov r0.w, c0

// approximately 4 instruction slots used (1 texture, 3 arithmetic)
