Introduction and Project Overview
[Autogenerated] in this list, we're gonna talk about the M I b color Alfa note. So the M I b color Alfa is really just a very simple way of extracting Alfa Channel information from an existing mental rate texture. So if you were Texter has any kind of Alfa Channel information which, in my case, this particular texture does. We can extract that by adding in the M I B color, often known that found inside the data conversion Tam. From there, all we have to do is simply double click on the color Alfa, take our texture, look up node middle click and drag it into the input and you can see immediately if your image has any kind of an Alfa Channel built into it. We can now extract that from here. So now we can very easily take this Alfa Channel information and use that for pretty much anything. So if we need this to be able to drive transparency or if there's anything else in our shading network that requires this Alfa Channel information, we now have access to that through the use of this am I be color Alfa note
