How to Bring back vignette effect to snapmatics

Open timecycle_mods_4.xml (update/update.rpf/common/data/timecycle) and search for phone_cam1. Remove all the values and then paste these ones:

    <postfx_desaturation>0.750 0.000</postfx_desaturation>
    <postfx_noise>0.000 0.000</postfx_noise>
    <postfx_vignetting_intensity>0.975 0.000</postfx_vignetting_intensity>
    <postfx_vignetting_radius>10.000 0.000</postfx_vignetting_radius>
    <postfx_vignetting_contrast>0.250 0.000</postfx_vignetting_contrast>
    <postfx_vignetting_col_r>0.024 0.000</postfx_vignetting_col_r>
    <postfx_vignetting_col_g>0.035 0.000</postfx_vignetting_col_g>
    <postfx_vignetting_col_b>0.047 0.000</postfx_vignetting_col_b>
    <postfx_scanlineintensity>0.100 0.000</postfx_scanlineintensity>

Also change numMods from 39 to 9. Note: you still need to toggle the filter (the first one).
