How to change the version of multilayer EXR at once.

PostThu Nov 07, 2024 7:44 am

In nuke we can split AOV passes with shuffle node, but in fusion we have to use loader node for each AOV passes. Is there a way to easily split AOV passes in fusion.
But my main issue is if suppose I use multiple loader to split AOV, if I need to change the version of my EXR I have to relink every loader node. In nuke I can relink this with only relinking the single read node and it will be updated on every shuffle node if the AOV name is same. Is there any way.

It's not as easy as it is in Nuke, but there are some user-made scripting solutions. I'm not sure if anybody has generalized my Version Control scripting adventure, but check this thread at WSL: https://www.steakunderwater.com/wesuckl ... hp?p=13878

And Reactor should have HOS_SplitEXR, which does the work of making a Loader per AOV.

Thanks for your reply.
I'm already using HOS_SplitEXR. But to change the versions I have to change all the loaders. Which is a hassle. Anyway I will look on to it.

I wrote a couple of scripts to help stuff EXR channels into the loaders extra channels and to extract a 'Channel' from the loader. Not pretty but they save time, you may need some basic scripting skills to reconfigure.

Yet another script promotion haha

You can use my Change Strings script. It's got a simple versioning tab to increase or decrease versions of selected loaders/savers etc.

This is it in action, you need to jump to 02:25 to see the versioning. Unfortunately, the jump to the correct part doesn't work in this forum:


You can download it through reactor or my gumroad.

At some point in the future there is also going to be an update to it in which I want to (along with other improvements) support pretty much any filepath fields that currently and in the future exist in Fusion. Right now it doesn't support the USD and LUT Tools for example.
