Nuke 101 book

[kht]

I bought this book because I just wasn't getting much out of the foundry's education materials.

I've already encountered two mistakes in chapter 2 and one I can't get past. Basically I have 3 files being read into merge and write/viewer, but one of the files is an RGB that only has info in the r channel.

According to the book, when I enter R into the R,G,B and A channels inside the shuffle node this should allow me to take the info from red channel and force into the alpha channel. (Since the original mask file doesn't have an alpha, and only has info in R, not G or B).

I need this to work as it's a part of the mask I need to finish the composite but after following the instructions (listed above) and trying some things on my own, nothing happens.

Yes, this read file and shuffle are plugged into merge->write-> read->

in advance!

If you are sure about the mistake, do follow it up in Foundry Nuke mailing list as the author of this book is quite active in there.

I dont have the book but setting the shuffle to r for red, green, blue and alpha should fix your problem


Shuffle {
green red
blue red
alpha red
name Shuffle1
selected true
xpos -171
ypos -78
}
