Brush, Healing Brush, Clone Stamp has Current/Bellow Option.
If i work two layer something like
Top layer : Noise or Grain something like Texture (Its Clipping Mask to Bottom layer, Effective only Bottom layer) Bottom layer(Blank New Layer) : paint or blend somthing use Mixerbrush
If that tool has Current and bellow, I can just paint or blend use MixerBrush on Bottom layer.(Because, Clipping mask effect only where i paint)
But, Until now MixerBrush only have "All Sample Layer". So, if i want that effect... i have to turn off layer (TopLayer), And then Paint or Blend use mixerbrush(bottomlayer). And if finish MixerBrushing, Turn on Top Layer. If I don't turn on and off the eyes of the layer like this, the noise layer above is mixed.
The brush can be applied comfortably without this process, but there are times when you want to use a blender brush. So I suggest to Adobe Developer. Could you put this option(Current/Below in to MixerBrush Tab) in?
