; Parlaklık ve offset
mul r0.rgb, t0, c0      ; r0 = t0 * brightness
add r0.rgb, r0, c1      ; r0 = r0 + offset

; Renk tonlama
mul r0.rgb, r0, c2      ; r0 = r0 * tone

; Fog karışımı
lrp r0.rgb, c4, r0, c3  ; r0 = (c4 * r0) + ((1-c4) * c3)

; Specular highlight
add r0.rgb, r0, c5      ; r0 = r0 + specular

; Alpha dokudan
