    Softedge - Black level lift

    by MatteLe » Wed May 13, 2026 11:23 am

    As we all know, in Softedge areas the blacklevel of overlapping projectors add up and give some gray on black scenes. To egalize this, the blacklevel in the non-softedge areas could get liftet to match the added blacklevel more. For now, I see no easy way to construct something like this in madmapper (correct me if I'm wrong, the ugly solution could be to add some 3% opacity fethered white quad to these areas, but this impacts also the brighter parts of the image), but it could be easily implemented since the softedge areas are defined. Maybe it could also be done with some FX shaders?

    I agree, this can be quite noticeable in dark scenes. It would be great if MadMapper had a built-in way to compensate for the raised black levels outside the blend areas.
