TL;DR
Meshy Edit is a mesh-editing model from Meshy that changes only the part of a 3D model you select and leaves the rest untouched. You circle an area, describe the change in one sentence, optionally add reference images, and get a new version of the model.
It fixes a common frustration with AI 3D generation: when one detail is wrong, the usual choices are regenerating the whole model or opening Blender and fixing it by hand. Meshy Edit adds a third option: edit your 3D model with words.
The problem: one wrong part means a whole new model
AI 3D generators are good at getting you most of the way there. The trouble is the last stretch.
Say you generate a knight miniature for a tabletop game. The armor, the pose and the face are exactly right. But there's an extra strap hanging off the shield, or the helmet is missing the plume you pictured.
Until now you had two options. You could regenerate and hope the next result fixes the strap without changing the face you liked. In practice, it usually changes everything. Or you could export the model to Blender and fix it yourself, which means learning mesh editing for what should be a five-minute change.
Game developers hit the same wall from the other side. The character design is locked, and now you want the same character in a different helmet or holding a different weapon. Regenerating gives you a different character in a different helmet.
The root issue is that most generation workflows treat a model as one indivisible output. There's no way to say "keep all of this, change just that."
What Meshy Edit is
Meshy Edit is a dedicated mesh-editing model, released on October 9, 2026 and open to all registered Meshy users. It is not a Pro-only feature.
You select a region of a model, describe what should happen there in plain language, and Meshy Edit generates a new model in which only that region has changed. Everything outside the selection stays the same.
It handles three kinds of change:
- Add a part, such as a hat, a plume or a handle.
- Remove a part, such as an extra strap or a stray spike.
- Replace a part, such as a crown with a top hat, or one helmet with another.
When words aren't enough, you can attach reference images showing what you want.
How to use Meshy Edit, step by step
The whole flow is: enter Edit, select an area, describe the change, generate, and get a new model.
Open Edit on a model you generated in Meshy. In the Print module (Meshy's workspace for getting a model ready for 3D printing), Edit is the opening card under Post-Processing and the main button in the Editing Bar. In the model viewer, it's the main button in the Editing Bar.
Select the part you want to change. The Lasso is the fastest tool: draw a loop around the part on screen and it selects the whole part's mesh, including the front, sides and back, so you don't need to rotate the model to catch every face. Then use the Brush to paint visible surfaces and refine the edges.
- Made a mistake? The Lasso Eraser deselects by looping, the Eraser deselects by painting, and Clear All wipes the selection.
- The selection doesn't need to be exact. Meshy Edit cleans up the edges after you submit.
Describe the change. Write it the way you'd say it to a colleague: "add a small top hat", "remove the strap on the shield", "replace the helmet with a horned helmet". You can also attach up to 5 reference images, 20 MB each.
Generate. The edit runs in the background, so you can leave the page and you'll be notified when it's done. Each edit costs 20 credits. If it fails, the credits are refunded automatically, and one-tap Retry reloads your selection and description.
Keep going. Your original model is always kept. The new model can be edited again, downloaded, or sent straight to print.
One more detail: if you skip the selection entirely, Meshy Edit treats your description as a whole-model edit.
In the Print module, Edit is the opening card under Post-Processing and also sits in the Editing Bar.
In the model viewer, Edit is the main button in the Editing Bar.
Scenario 1: fixing a figurine before you print it
3D printing is where single-part problems hurt most. Every flaw in the mesh becomes a flaw in plastic or resin, and a reroll can cost you a model you were otherwise happy with.
Take a capybara figurine for your desk. The body, the pose and the proportions are right, but you want it wearing a top hat. Lasso the top of the head, type "add a small top hat", and generate. The capybara stays the same capybara, now with a hat. From there you can send it straight to print from the same flow.
Removing works the same way. If a bust comes out with a stray element on the shoulder, loop it, type "remove the extra piece on the left shoulder", and generate.
This is where Meshy Edit is most predictable. Worn accessories like hats and glasses, and swaps between similar shapes, tend to give stable results.
Scenario 2: one game character, several versions
For game developers and character creators, the problem isn't fixing a mistake. It's making variants without losing the character.
Start with the knight from earlier: sword, shield, full plate. You want a few versions for different loot tiers. Lasso the helmet and type "replace with a horned helmet". Generate. Same knight, same face, same armor, new helmet.
Because every edit creates a new model and keeps the original, you end up with a small family of versions branching from one base. You can also edit an edited model, so changes stack:
- Base knight
- Knight with a horned helmet
- Knight with a horned helmet and a round shield
Weapon swaps work best when the new item has a similar shape to the old one, like a sword to a mace. Large shape changes and items held away from the body are less predictable, so expect to run those a few times.
Meshy Edit vs. regenerating vs. Blender
Meshy Edit is the right choice when the change is easy to describe and you want to keep everything else as it is.
| | Meshy Edit | Regenerate the whole model | Manual editing in Blender |
|---|---|---|---|
| What changes | Only the selected part | Everything | Whatever you touch |
| What's preserved | The rest of the model | Nothing is guaranteed | Everything you don't touch |
| Skill needed | A rough selection and one sentence | Prompt writing | Mesh editing and sculpting |
| How you iterate | Rerun the edit and compare; every version is saved | Reroll and hope | Rework by hand for each change |
| Your original | Always kept | Replaced by a new result | Kept if you saved a copy |
Blender still makes sense when you need exact dimensions or fine control over individual vertices. For the common case of "this is right except for one part", Meshy Edit removes the detour.
Tips for good results, and what phase 1 doesn't do
Results vary by type of edit. A few habits make a clear difference:
- Select a little more than you need. Include some of the neighboring area so the new part blends into the model.
- Describe the shape, not just the object. Words like "thicker", "rounder" or "shorter" give the model something concrete to work with.
- Run the same edit a few times. Each run is saved as its own version, so you can pick the one you like.
- Start with stable edits. Worn accessories and similar-shape swaps are the most reliable. Objects held away from the body and large shape changes are less predictable.
This is phase 1, and the scope is deliberately narrow:
- It works on Meshy-generated high-poly draft models. Uploaded external models, textured models, split results, animated or rigged models, and assets that are still generating aren't supported yet.
- It edits geometry. Texture and color editing are planned for a later release.
- There's no API access yet, and timing hasn't been announced.
FAQ
Is Meshy Edit free? Who can use it?
Meshy Edit is available to all registered Meshy users and is not a Pro-only feature. Each edit costs 20 credits, and the credits are refunded automatically if the edit fails.
Which models can I edit with Meshy Edit? Can I upload my own?
Meshy Edit currently works on Meshy-generated high-poly draft models. Uploading external models isn't supported yet, and neither are textured models, split results, animated or rigged models, or assets that are still generating.
Can Meshy Edit change textures or colors?
Not yet. In phase 1, Meshy Edit changes a model's geometry. Texture editing is planned for a later release.
Is my original model kept after I use Meshy Edit?
Yes. Every Meshy Edit run creates a new model and keeps the original. The new model can be edited again, downloaded, or sent to print.
Does my selection need to be precise?
No. Meshy Edit handles the selection edges after you submit. The Lasso selects a whole part through to the back, and the Brush refines the edges. If you make no selection, Meshy Edit applies your description to the whole model.
How long does a Meshy Edit take, and what if it fails?
Meshy Edit runs in the background, so you can leave the page and get notified when it's done. If an edit fails, the credits are refunded automatically, and one-tap Retry reloads your selection and description.
What if the Meshy Edit result isn't what I wanted?
Try a slightly larger selection that includes neighboring areas, and describe the shape clearly, for example "thicker" or "round". Running the same edit a few times also helps. Worn accessories like hats and glasses usually give the most stable results.
Is Meshy Edit available through the API?
Not yet. API access for Meshy Edit is planned, but timing hasn't been confirmed.
Wrapping up
The hard part of AI 3D generation has shifted. Getting a decent model is no longer the bottleneck; changing one thing about it without losing everything else is. Meshy Edit turns that into a selection and a sentence.
If you have a model that's almost right, that's the place to start. Open it in Meshy, hit Edit, loop the part that's bothering you, and describe what it should be.
