Hello,
I've seen a similar post with no answer, so I wanted to create a new, more detailed post.


I have a problem with the z-depth pass exported (32bit .EXR) from octane.
With Frishluft (or an other plugin), the edges are jagged.
Because this pass seems to be anti-aliased, and to use it in after effects, it should be aliased.

So, what I do know is export my z-depth pass with Advanced render, and I get a better result.

Here are a screenshot to compare the compositing in after effects:

So, Is that an octane core problem, or it can be solved by the fabulous Aoktar ?

Thank you

Try setting the Filter size to 0 instead of the default 1.2 also try using a position pass instead I thing that one is Aliased for sure.

Thanks Terry,

I've just made the test, and it's the same, as you can see in this picture.



I thought that it Will work.

Here's a tutorial on using a position pass instead of a depth pass to achieve a better result

http://greyscalegorilla.com/tutorials/y ... -is-wrong/

This is exactly what I did.
As you can see in the tutorial, he export the P.Pass from advanced render, and he has no problem in the result.

In the past, I hadn't no problem when I wanted to export the Z-pass/Position Pass from Arnold, or vray...

So If you do the test now, you will have the same result as me...


Aoktar, are you there ?

Well I'm scratching my head right now then, seems like the best thing to do is use the default renderer for this which is perfectly fine but still I would like to know a way to fix this inside the engine.

Yes lol, I'have been trying since a long time too.... I think it's crazy if there is no solution... For a top notch render we should get a proper Z/P pass

If you use only 1 sample for info pass and filtering to 1, your info passes are aliased.

Good Idea Calus,
So I've tried with one sample and the issue is worn edges now.



It's better, but it doesn't really work

I've tried with 4 - 8 -10 -15 sample and the result isn't better.

right , not really usable
but as far as I know 1 sample is the only way to have aliased passes with octane.
