Hi guys! I don’t understand how the alpha channels may works on texture.
I’m trying to convert the black part of a texture in transparency, but it simply doesn’t work, no matter which node I use (Keying, SetAlpha, AlphaLevels, RGBA, LumaKey)
Perhaps I don’t know how to use them?
In the patch attached, my idea is to “Keying” the black background of the TEXTURE2 in order to have the six white square over the TEXTURE1, but I always obtain only TEXTURE2
this is an example, not my real patch. In the real, textures are given and I cannot modify them <<<
I already tried the two solution you wrote, but unfortunately the problem is way more complex, because the real patch is not Black/white and involve lots of rotating mesh in more level etc etc.
What I wanna achieve is something like this: here I used, instead of the generated texture, the same image but made in photoshop, with transparency instead of black. It works, even with the Blend mode not in multiply , or add
My question is: it is possible to do the same operation inside VVVV? I mean, convert all the BLACK from an image in a alpha channel?
