I made my own Mask render presets.. White backgroung, eksposure to minimum, contrast to max, wind = 0 (important), all whether related settings = 0 (didn't touch light brightness), no image effects (blum etc)..
It gives good mask but takes to render almost the same time as a proper image..
I need it for post processing.. For placing my model on foto of project's site..
I used Twilight before.. they had whole bunch of predefined technicall kind of render types.. Mask, Depth, diffuce pass, light pass.. etc.. It was very helpfull for postprocessing.. As well those technical kind of render used to take much less time..
