@Clément Foucault (fclem) I guess this is by design of the new Pixelate VFX and not related to Antialiasing, right?

In previous versions of the program, in Preference - > Viewport there was an anti-aliasing item for Grease Pencil (I don't remember what it was called, but it seems to be " Grease Pencil Anti-Aliasing")

sorry I made a mistake, here I downloaded the last version of the program:


Grease Pencil Multisampling. Where is this button now?

@andrai (ihni) In 2.83 you have two options.

This disable AA.

And the threshold parameter to change how works.

I have tested using the simplify and it looks the pixelate effect is what created this AA effect, not the antialiasing itself. The problem with the old Pixelate VFX was that it was wrong, so the current implementation is the right one.

This disable AA.

it doesn't work :(

I want to find "Grease Pencil Multisampling" and disable it.

Antonio Vazquez (antoniov) added a comment.Jun 23 2020, 4:24 PM

As I explained you above, the antiliasing effect is not produced by AA, but by the Pixelate effect itself. If you disable AA in a stroke without Pixelate, you will see the diffference. The old Multisampling value in user prefs screen was removed because this is not used anymore.

So you won't be able to make vector pixel-art in the new blender? :(
Sadly...

We could add a checkbox or a sample parameter to use nearest neighbor for this effect.

@Antonio Vazquez (antoniov) this should be very easy for you.

andrai (ihni) added a comment.Jun 23 2020, 5:50 PM

that would be great. But because of one person it is unlikely to be added to the program

Antonio Vazquez (antoniov) claimed this task.Jun 23 2020, 7:06 PM

@Clément Foucault (fclem) yes, I will implement it.
