I don't know how many of you use shade paints, but I use them now more than I ever used to, and recently found something interesting that I don't believe is documented anywhere, and possibly not many people are aware of.
You see, my most used paint is a set of a couple of hundred colour images ... just plain colours, but they can be used to great effect to highlight area's. However, there's no apparent way to use an image as a shade paint.
I used to draw a paint break box inside my shade break boundary, paint inside the paint break box and then edit the paint to be a shade, and finally delete the paint break box.
But ... recently, I've accidentally discovered a much quicker way ...
Select PAINT LINES and choose a paint pattern, and then check the shade paint box. Then WITHOUT painting anything select PAINT IMAGE ... and this is the undocumented part ... as long as you don't do anything except PAINT, the previously UNUSED "SHADE PAINT" checkbox remains active, so you can use IMAGES and MODEL PAINT as shades without any intermediate steps.
Who knew ... ?
