When using CoronaMix, with Mix Operation set to “Divide”, as a pattern map for Chaos Scatter the density of the objects is extremely high, inconsistent with other mix operations and scatter “Count/Per Square” settings.
I guess it’s simply a case of divide blend output getting higher than 1. Did you try to plug an output map after Corona mix and toggle clamp option? I think that should bring the scatter result to what you’re expecting.
P.S. maybe we can request a clamp option in Corona mix map itself?
