Hello, I am working in Opentoonz 1.7 with the Raster sketch brush in a toonz raster level. I am making new drawings in blue in the same level drawings (level frames) as I did for the pink lines. However my blue lines are shown to be made UNDER the previous pink lines. I see no optional settings for the 'sketch brush' to have the new lines to be drawn "over all' as in the default 'no brush' settings. How can I get my current lines to go over the older ones?
