@Josh Tucker: Sorry for incovience caused. We are aware of this bug and will try to fix this at our earliest ease. Thanks!.
Workaround: Please make the size of the object smaller.

@Dale Iannello: Can you please help to explain where it is crashing for you?
Also please help to provide the complete repro steps with ai file so that we can fix this at earliest. Thanks!

I don't think you guys understand the purpose of vectors. the reason i use .ai is so the output is fully scalable and it can be expanded and taken apart. all you've done is put a little raster window in a vector world. You can't use it as a vector because it's not a vector anymore. The 3D classic was getting there but instead of fine-tuning it so it worked right you gave up and stuck this weak photoshop code in there. These are not vectors. The renderings are unpredictable and look bad. There's nothing good about this feature. Years ago there was a plugin for illustrator called "Be Infinite" It was amazing. Back then Illustrator was a great tool and with Be Infinite you could do anything! Quickly. you've made this program slower, buggier, and harder to work with than the earliest versions of illustrator. I think you decided to make it for beginners but you keep adding useless features. And trying to trick us into putting our personal files in your cloud. in this latest update, you say you can change colors in real time. We could already do that! that's not a new feature! Step and repeat? That's one of the most basic functions and you think you invented a new feature!!! Learn what illustrator can do already before you try to improve it! I don't think you have anyone there who actually draws with illustrator because you keep making it harder to work in production. Plus these long delays and lags make it impossible to meet deadlines!

So, the older Illustrator 3d function gave you the option of where to place the graphics. In the new one I can't find any way to do that. Makes it really not very useful.

It keeps on crashing! All I'm trying to do is add text to a graphic.

Sto riscontrando un problema quando raggruppo gli oggetti esce questa scritta ( vedi allegato ).
Il 3D mi funziona solo per singolo soggetto.
Saluti.

While I'm editing, the object looks exactly how I want. But as soon as I stop editing, it duplicates the object and chops it in half and it's all wrong. If I expand appearance or try to export or anything, I get the messed up version - not the correct thing.

Would be great if there was a way to create your own default settings for Lighting. Is this possible?

Hi! I've been trying to inflate some paths and export to SVG, but the 3d and materials effect won't let the background show through, even though, in Illustrator everything looks fine.

Attached is a file demonstrating the distortions that occur when using the new 3D mapping on letters or shapes with negative spaces. This is not the original file I started with, but I wanted to make sure I was getting the same results. I've tried different computers as well. Thanks for any feedback you can give.

Egor,
Thank you for getting back to me and sorry it took so long to respond. It's the end of the semester and I've had other concerns. Attached is a file demonstrating the distortions that occur when using the new 3D mapping on letters or shapes with negative spaces. This is not the original file I started with, but I wanted to make sure I was getting the same results. I've tried different computers as well. Thanks for any feedback you can give.

Mona, Twist and Taper is going to be released in 27.1 in this December. 27.0.1 is one minor version away from it :)

My latest version of illustrator 27.01 doesn't have twist and taper options.
Why not?

Is crashing my MacBook Pro, running BigSur (11.6.7)
AND has now lost the effect in the Appearance window! The effect is still there on the object, but clicking the object I don't see the "crosshair" icon. And going to the Appearance window, the effect is not there, so I cannot alter it further. AND if I try to add the 3D Bevel effect again, I get a warning saying only some objects are supported and that I can't apply a second effect. Yet it does show now in the Appearance window, but it isn't the one that is being applied! So I cannot get back to the effect to alter it or even remove it.

While it's nice for some effects, I much prefer the output of the classic vs. the new. Here's a quick test I did of two objects. The new 3D sometimes introduces inexplicable cutoffs (see the left and right side of the blue pill shape) and when a common perspective is assigned to separate objects, things quickly fall apart as opposed to the classic, where all the pieces maintain their common references and can therefore be easily built into 3d objects. For a more extreme version of Classic's ability, check out https://www.artstation.com/artwork/ykvP63. PLEASE, for the love of all that is good, NEVER get rid of Classic.

In this new feature of 3d and Materials, I think you should Add perspective distortion of the DEPTH, to give that optical illusion of depth when you increase the amount.

Not liking this update at all. Classic layout was much better. Functionality-wise, my shapes aren't retaining the information for the bevel presets I've input so that I can re-edit and adjust once they're in position on my artwork plus, if I alter the shape proportions (i.e., enlarge the shape) I can't customise the bevels to maintain consistency with the smaller shapes. Also, there doesn't appear to be an option to re-set the shape so that it doesn't have 3D settings applied, so you have to recreate the shape from scratch or constantly have the target symbol appearing on your shapes. Very frustrating.

The 3D mapping feature does not work if there is a path that has been used as a negative space. Say, like the inner triangle in the upper case "A". If I want to map an image on the front face of the letter, the mapping feature doesn't work. Any image that is mapped creates digital garbage in the mapped image. I have found that this seems to only be a problem with an inner path of a form that used the Patherfinder "minus front".

Thanks, I'm not finding the panel where option "map art" is

Pretty good thing overall. But how do I make multiple light sources? Really, how do you imitate 3D with only one light source and 4 presets for it?
