Vectors get pixelated after 3d effect(Rotate) in ver. 26.0.1

[Mohamad Ahmadi]

Hey there

I've a problem with last version released lately when I apply 3D effects, the shape is originaly created in illustrator and I've done this many times before but in this version it get pixelated.

for our surprise, it's not completely pixelated. a side of the shape gets pixelated but the other side stays vector.

even in a line of the side it's partly pixelated and partly vector.

I would really appreciate if you can help me with fixing this.

I attach the shots to get this better.

Thank's.

Additionaly, I checked it on macbook pro (my laptop is asus) and the problem is still there.

Do you use the new 3D effect or the classic version?

[Mohamad Ahmadi]

In this case I've used the classic effect.
But I tested the new version 3d effects and this problem occured too.

If there are dradients involved, Illustrator probably cannot render your objects in pure vector.

Set up a higher doument raster effects resolution.

Please tell us details about your objects if there are no gradients involved.

[Mohamad Ahmadi]

It has gradients but I've used this effect before exactly on this file but after updating I've ran into this problem.

[Monika Gause]

Without knowing exactly how the object is built, it's impossible to help you.

What are the Document Raster Effects settings?
Are you using GPU or CPU preview?

[Mohamad Ahmadi]

At first the GPU performance had been off then I turned it on but the problem is still existed.
