Meshy adds text-prompt edits for selected parts of its AI-generated 3D models

A hat can come off a generated 3D character without asking the AI to rebuild everything else. That is the promise behind Meshy Edit, launched October 16, 2026. The feature lets users select a region and describe a change in plain language; Meshy says it preserves the rest of the model.

The feature runs on a new AI model built in-house. Meshy positions it as an alternative to regenerating an entire asset or changing its mesh—the structure defining its shape—by hand in software such as Blender. Its intended users include 3D-printing creators, game developers and character artists.

Select the part, then describe the change

Editing starts from a generated draft in the Meshy workspace. The Lasso tool selects through the model, capturing the front, sides and back of a part. The Brush tool refines selection edges on visible surfaces. Meshy says exact boundaries are unnecessary because the system refines them after submission. Without a selection, the instruction applies to the whole model.

The instruction can be as short as “remove the hat.” Users can also attach up to five reference images, each no larger than 20 MB. Meshy recommends simple shape descriptions, such as making a part thicker or rounder.

Meshy says an edit usually takes about a minute. Processing runs in the background, with a notification when it finishes. Each edit creates a new model and keeps the original. Results can be edited again, downloaded or sent to slicer software, which prepares models for 3D printing.

The supported starting point is a Meshy draft

The feature supports high-poly drafts—models with detailed polygon meshes—generated with Meshy 6 or Meshy 7.1. Ultra 2K models are supported, but Ultra 4K, low-poly and externally uploaded models are not.

Meshy’s help center lists textured models as unsupported. Its launch announcement says those assets automatically switch to their untextured version for editing.

Other unsupported assets

• Separated parts.
• Rigged or animated models.
• Assets whose generation is still in progress.

Credits, retries and developer access

Meshy Edit is available to all registered users, not just Pro subscribers. Each generation costs 20 credits. Meshy’s help center says credits are automatically refunded if generation fails. A one-click retry reloads the previous selection and description.

For unsatisfactory results, Meshy suggests repeating the edit, widening the selection to include surrounding areas or making the shape description clearer. It says accessories attached to a body, such as hats and glasses, generally produce reliable results.

Developer access is still pending. Meshy’s help center says there is no Meshy Edit API yet and estimates availability in early December 2026.
