DO THE SHUFFLE

UPDATE 21/04/2022 - fixed a issue where if current layers where not present in a render it would refuse to run :) but all fixed now so it should be fine

One of my larger python projects, Do the Shuffle, is a utility gizmo that makes working with CG renders a lot easier. Made up of 2 sections, I will explain how it works below.

Something to keep in mind, in order to save bloating and other issues, this technique doesn’t work with cryptomatts. This is because these layers can get mad, so it just made sense to remove cryptomatts.?The other thing is that I have only really been able to test this out with Arnold renders, it may/probably will work with the other major renderers, but the utility passes may not work unfortunately. also it utilises the new shuffle node, if wanted i could add a old shuffle node into it b

Picknick -

This was created due to a comment by one of the VTs about how, in industry, they render out each pass separately, which is recommended for speed reasons. This lead to the creation of the sandwich system that you can use to either write out each layer separately before recombining them back into the script, or by recombining single layers. When you press the write node button, it will create all the needed write nodes with their own folders, (if folders are already present then it will just render into them). This part follows a naming convention, where the subfolders and EXRs need to be names the same thing. This means that if you have already separated EXRs, you may need to rename them but once this is done you can press the sandwich button and it will re-combine all of the layers inside that folder, hopefully making it faster to work with!

Do the Shuffle -

The main part of the gizmo is this set up. It is used to quickly create a bunch of postage stamped shuffle nodes with each beauty and utility pass shuffled out as well as a 'primitive' shader rebuilder that I will discuss below.

With the Break it Down button you have a couple of options, you can have it just shuffle out the utility passes (n depth and p), or you can also have it just shuffle out the major lighting shading groups, or you can do a full light break up where it will break up the light groups into each light pass with the option to add a remove node to each of these. There is also have the shader rebuilder, this creates a shader tree with all the light passes first merged to each other then into each group, it only currently works with diffuse direct, indirect and spec. It’s not laid out in the nicest way but may be a good starting point.

I’m sure there will be issues with this so if you find any please let me know!

Hopefully you guys find it useful
