Duplicate Cryptomattes

[rusty_sena]

Hi all,

I have a scene that I've been importing lots of models into and they are all coming with materials. I've created only 1 cryptomatte render output but for some reason there are 3 of them in my vray VFB. I can't find them anywhere in my Modo shader tree. I did see a post that someone made where Vlad instructed him to use a couple of commands to find them and parent them but that did not work for me. I still have these unwanted extra cryptomatte outputs. Can anyone help?

Thank you!
Rusty

I replied on the Foundry forums, so I'm just pasting it here:

If you look at the v-ray cryptomatte render output, it has an "outputs" section. VFB will show each enabled output as a separate layer.

It sounds like you just have all the outputs enabled. Is this what youre seeing?

Hey, Rusty,

I think John and Volker answered you about it of course if that is your case unless please let me know and add more details. In case that you're used PS or Affinity, you can control the extra tag layer from the Levels option If you are using it with Nuke, that won't help you.

Cheers, and be healthy.

Can you link this post ?

The cryptomatte item has a different "type" than normal render outputs, that's probably why it didn't work.

In order to select all the cryptomatte items, including those not accessible in the shader tree (which you see in the VFB), you need to execute this command:
select.itemType material.vray.cryptomatte

Then you can hit delete to delete them.

Thank you Vlad. Funk posted the same thing on the Modo Forum. I don't know anything about scripts but is this something I can make into a button or something?

[vladimir.nedev]

Sure, you should be able to make a button out of it, but I am fuzzy on the details.
Otherwise, you can execute it in the command window ( F5 ).
