Painted Shader impacting coverage?

[billg60]

I am have a situation with painted shader that I do not understand. I am using an almost identical group of shader layers that varies only by the slope filters and applying a painted shader as a blender to the one group. I am trying a achieve a variation in my scene where some areas have grass coverage on steeper slopes than most of the scene. (I have this situation in my real life reference photo) I setup the two identical groups and only adjust the slope coverage on the one group and apply a painted shader as a blender to this second group. What I am seeing is that unless I adjust the coverage in the layers of the group that is using the painted shader, the coverage is much lower than the original group. e.g. I have to go from coverage .8 to 2 to make the second layers have any impact. This makes it very difficult to match the overlapping shading with the original group which is my objective. I have rebuilt the painted shader in case there is some density question there but it had no impact.

I have included a clip of the nodes in question as the overall project and terrain DEM is quite large. Any help is appreciated.

The Coverage slider in the Paint shader dialogue might be having some impact...have you set it to 100%?

Try changing the colour of your painter shader to white.

So the color of the painted shader impacts the density of the region represented in it? That explains a lot of mysteries I have been having with painted shaders. I thought it was just a preference when drawing the region. I have all kinds of pretty colors for my painted shaders... but none of them white. Thanks so much!
