Cant assign Object ID´s

[marcus.olssonWHNTA]

Hello,

I´ve asked this question earlier but I try once again:

I want to assign object ID´s to some objects.

I´ve tried a lot but I can´t manage to get individual colours on the objects when rendered.

So thankful for help!

Thank you in advance.

Which plugin? Have you tried the ID AOV and/or Utility shader?

[marcus.olssonWHNTA]

Actually i don´t know exactly which Plug-in I Use. I haven´t download any so to say.

Under the "built-in rollout" I´ve used both the "object" and "ID", I think the problem is that I don´t know how to choose and assign ID´s to the specific objects.

MAXtoA? You can download the latest version of the plugin here.

Tutorial here.

AOVs

Utility shader

[marcus.olssonWHNTA]

Yes I have MAXtoA plug in.

Which of the AOV, in the builtin rollout are the best to use if I only want to "separate" some of the objects from the others? (in the render with different colours) And how can I assign it to the specific objects?

So thankful for your help.

Did you try the aov_write_rgb as in the tutorial?

[marcus.olssonWHNTA]

Hi,

I try now and I think everything is fine, until I should "Open the Render Settings window and under the AOVs tab, select 'Setup AOVs'". I cant find the setup AOV tab.?

But I can see that I have the "ObjectID" under the custom rollout.

Therefore, How can i move forward and assign it, You with me?

Hello Again,

After looking at the Tutorial, They are not showing how to assign the object ID´s, Will arnold do it automatically?

Br,

Have you tried ID AOVs in the Standard Surface?

[marcus.olssonWHNTA]

When i look in the standard surface, I can´t find the AOV rollout in the bottom.

Everything else is exactly the same, but I miss the oppurtunity to choose "colourID"

I can add to the conversation that i´ve used the Arnold material, Is that a problem or could I still render Object ID?

[lee_griggs]

Have you installed the latest version of the MAXtoA plugin?

[marcus.olssonWHNTA]

I will install it and check, Hopefully it´ll help me!

[marcus.olssonWHNTA]

I´ve now downloaded the plug in and got all the functions as I need.

My Question is right now: How do I compare the different ID´s (in the rollout where I can choose colours) with the objects I will pick pick in the render set-up window. (Where I add Custom AOV´s)

[lee_griggs]

You can assign different Standard Surface shaders to different objects with different IDs. The workflow is here.

[marcus.olssonWHNTA]

Okey. Just to ensure: In The standard surface rollout, i write ID1 with pink colour, Then in my Custom AOV I create a new AOV called ID1, I add it to the object i want to have an Object ID on, I press add " channels" , Is that workflow right and can i expect it to render out the objects with dif. colours?

[lee_griggs]

Yes, but you set the color yourself. Maybe Cryptomatte is more suitable for your needs?

[marcus.olssonWHNTA]

Yes, The problem is that I don´t know if it generates the AOV´s since i can´t see them in the render, but i got files like .AOV in my output..

[marcus.olssonWHNTA]

It Seems that the Cryptomatte works good, that gives me separate colours for the objects I want. !

But i´m still unsure how to do the render process, in case of both get the "cryptomatte" separation and the "proper" look..

[lee_griggs]

"and the "proper" look.."

Do you mean the RGBA AOV (beauty)?
