    Question Is there any way to make it draw on another layer than the density map?

    And back at 100%, but with a jitter of 1. The jitter value is a scale of the spacing parameter, for randomly displacing the x&y directions, to get rid of the grid look:

    The scrip draws left to right and top to bottom, to work with isometric image brushes, like the trees posted:

    And using the "invert" check will invert the map (black = 100% chance and white = 0% chance):

    I believe RobA gave the answer in the first post under the second thumbnail:
    Create a new layer (it must be the same size) to draw on with the current brush.

    Please take my critiques as someone who Wishes he had the Talent

    Could someone please be elucidate?

    In particular (where to start?),
    * well, when is a brush wanted to be transparent(?) with solid backgrounds? (Forgive me, I don't even know if this means the brush has a solid background or that it is transparent when used on solid backgrounds)
    * and how making them in color [defining the the GIMP .xcf project file using a colour palette?] effects that behavior, as compared to using black-and-white
    * and regarding the "B&W outline ones," does this refer to a white tree on a solid black background (defined in a color project) or a white-tree-with-a-(narrow)-black outline on a transparent background

    I apologize for my denseness, but thank you for your forthcomingness.
