Well, out of context right now I'm not sure but, for the example of Xavier's composition, if I had a list of shaders, and I would want a specific range of the shader list to be replaced, how would I do it without ranges ?
And he wanted the items to be replaced not always to be the same but to change.
If for example there was a Replaces Ranges In Lists with drawers, I could make a range from 2-5 for example and fill a 5 shaders list that would place itself at positions 2-5.
How would I be able to choose the position of the items to be replaced ?
Another piece — "select a bunch of pre-connected nodes, right-click them into a macro and all publishing and cable connections are done for you" — doesn't have a public feature request, but we're already working on it and are planning to release it in Vuo 1.3.
One reason that you might see banding is if your monitor supports fewer colors. If that's the problem, adding some noise (as in the attached composition) should help.
To check if you really are getting an 8bpc image, you can open it in an image editing application and check the number of unique colors. For example, in Photoshop, go to Image > Mode > Indexed Color. The maximum unique colors you could see with 8bpc is 256. If you see slightly fewer than that (like 246), it's fine. If you see a lot fewer, there's a problem.
