I open a new post to better recall the subject; the discussion in the
post "CinGG's Youtube channel" is off topic.
I tried to repeat Igor Valdimirsky's tutorial; maybe I did something
wrong but my result is not good. Already with the default overlay
(Normal) the result is not exactly the same as in the tutorial. For
example, the outline of the letters is all white while in the tutorial
there are plays of light and shadows that make it three-dimensional.
But the worst comes when I set the center track to "Multiply": a
completely wrong color comes out!
Thanks for testing!
be sure that for this test you use rgba-8 or rgba-float project. But I have growing suspection we really do some calculations differently, may be in more widespread/standard way but not like original Cin worked.
Can you try CinCV or CinHV too?
