MyPaint 2.0 alpha released with spectral pigment brush+layer mode

Compositing in a subtractive pigment-like way has been very confusing and a long journey. However, I think it is almost sorted out and would appreciate some feedback/testing. Download links include Windows and AppImage. The new layer mode is called “Paint”, and there is a slider to control brush pigment mode. I have yet to write up an article on the techniques, but it is essentially a modified Meng+Scott Allen Burns upsampling technique with a weighted geometric mean compositing of straight color. The alpha channel serves as the weights, normalized to sum to 1.0



Ooh, I’ve been looking forward to MyPaint 2. Looking forward to it.
