I have been looking for the equations used for all the blend modes.
In the Blender wiki there are descriptions, but no equations.
In Wikipedia there are equations, but there are more than one possible equation for few blend modes (ie soft light). I don't know which equation blender uses.
I also read this, however the Influence/factor not available on the equations.
It would be much appreciated if the list of equations used in blend modes with factor/influence is made available. Please point me to the right direction if it already exists. Many thanks.
