Hi everyone,
Illustrator's latest (26.1) update is now available for download from the Creative Cloud Desktop application. This release brings to you several exciting enhancements to 3D features and multiple bug fixes.
Check out the list below:

Bevel and Inflate both sides
With this new release, you will be able to apply Bevel and Inflate effects to both sides of the object.
Automatic 3D Shadow Alignment
Get perfect shadows for your 3D design and no need to manually set shadow bounds. When you create shadows using new 3D and Materials effects the effect bounds automatically extend according to the size of the shadow.
Rotate multiple 3D objects with different properties
You can now rotate multiple 3D objects with different properties by using either the widget or panel. It enables you to save time while working with mixed 3D appearance objects.
Please update to the latest build using this link - Check for the latest update.
I am locking this post. Please create separate posts to share your observations or feedback with us.
Thanks,
Srishti
