One of the things I have always loved about about PMNG is the way it handles alpha. It is always had a genius approach that the second color is always set to alpha but using the program I have found that is not the case. Here are the steps to repeat the problem.
1.draw anything with one color.
2.draw anything with the second color but only the second color.
- Using the brush grab tool right click to grab the image to turn it into a brush
. It should ignore the second color and make it transparent
but it does not
Please fix this was such a useful option.
