Glost's drip mark in 3D, its orange glaze still dripping, turns into fifteen models made in Glost, one after another: an oak barrel, a 1980s coupe, a slime as pixel art, a mushroom cottage as voxel art, a Corinthian helmet, a fighter plane, a knight as pixel art, a treasure chest, a lighthouse as voxel art, a desert locust, a dragon as pixel art, a tin toy robot, a retro rocket as voxel art, an 1800s carriage and a juniper bonsai as voxel art. Each one assembles from voxels that land as clay, a glowing line fires it finished, and then it plays its Glost rig: the coupe raises its headlights and opens its doors, the plane spins up its propeller, the chest lifts its lid, the robot waddles on the spot, the slime bounces, the knight marches and swings its sword, the dragon beats its wings and lifts off, and the voxel art moves too.

01 The problem
Meshy hands you a model.
Your game still needs an asset.
Image to 3D is a real leap: a prompt in, a textured model out in about a minute. Then the relay starts. Retopology in Blender, a fresh unwrap, textures made again, a rig that fits only some bodies, weights, a retargeted clip, and an import that lands at the wrong scale. Every stop is another tool, another file and another undo history.

01
Generate
Today
Meshy’s API leaves remeshing off and returns triangles by default.1 Strong light in the reference photo bakes shadows into the texture.2 Fingers can fuse or come out in the wrong number,3 and floating parts need cleaning up by hand.4
With Glost
Calls Meshy, Tripo, Rodin or Hunyuan when you choose, or TRELLIS.2 on your own GPU. Then it repairs holes, degenerate faces and flipped normals, and scales the mesh to the size in the spec.
geometry.generategeometry.repairgeometry.scale_to_spec -
02
Clean up
Today
Remeshing in Blender throws the UVs away, so you unwrap and bake again, and retopology by hand takes hours.5 One Polycount thread puts it at about half a day per 30 props.6 Meshy’s own guide says to decimate in Blender and build LODs yourself.7
With Glost
Remeshes to quads inside the spec’s triangle budget: 200,320 triangles to 5,000 faces in 1.72 s, 99.8% of them quads, mirrored when the model is symmetric. LODs come from meshoptimizer.

03
Unwrap and texture
Today
Meshy’s UV unwrap takes at most 40,000 faces and hands back an untextured model.8 The generated texture was painted for the old mesh, so it has to be made again.
With Glost
Unwraps with xatlas and checks flips, overlaps, padding and texel density. Textures are projected onto the new UVs from several views, seams repaired and albedo kept in range.

Rig
Today
Meshy’s API rigs humanoids that face +Z, with tails and faces left to you.9 Mixamo rigs humanoids only.10 In one test the hip pivots sat 5 to 15 cm off, so the feet slid.11
With Glost
Classifies the mesh, cuts fused fingers apart, fits a 70 joint skeleton, keeps each finger’s weights inside that finger, and tests T, A, fist, spread, squat and reach. Lids and drawers get hinges and sliders.

05
Animate
Today
A Mixamo T pose on Unreal’s A pose skeleton twists the arms when you retarget,12 and bones still get mapped by hand.11
With Glost
Retargets between Mixamo, Rigify, Unreal, HumanIK and Character Creator skeletons, with rest poses aligned, limb lengths compensated and feet kept planted.

Into the engine
Today
Meshy’s own guide warns that a model can arrive “100x too big” in Unity.4 Unreal reads DirectX normal maps while Godot and Blender read OpenGL,13 Unity URP wants smoothness in the metallic map’s alpha,14 and Unreal only picks up collision named UCX_.15
With Glost
Writes a profile per target with the right axes, units, handedness and normal maps, adds LOD chains and collision hulls, packs the maps, and imports every export again to compare it within 0.1 mm.

Cost and trust
Today
Meshy Pro is $20 for 1,000 credits a month. Through the API a textured model is 30 credits, a rig 5 and each animation 3, and unused credits expire.16 On plans below Enterprise, Meshy may train on what you make.17
With Glost
Runs on your machine first. A paid step shows its estimate and waits for your yes, inside budgets you set, and every step lands in one history that says who did it.

glost firing (noun)
The glaze firing: the last one, when the glaze melts into glass and a matte pot comes out of the kiln glossy and finished. It is the job Glost does for an asset.
02 How it works
From one sentence
to a file your engine opens.
Three steps, and the middle one is a sentence.
-
- 02
Describe the asset
Write what you need in plain words. Your agent turns it into a spec with acceptance criteria and starts building while you watch.
- 03
Steer, then export
Pick a concept, approve or decline paid steps, or take over in the viewport. Export for Unreal, Unity, Godot or Blender, and Glost checks the file by importing it again.
03 The build
Every step is a command
you can see, change or undo.
One barrel, eight steps. The agent and the app send the same commands, so nothing happens out of view. Pick a step to see what the agent ran and what Glost checked.
Step 01 of 08
One sentence is enough
spec.create
“A weathered oak barrel bound with two iron hoops, about 70 cm tall.” Your agent turns it into a spec: dimensions, a triangle budget and the checks the asset has to pass.
Acceptance criteria are written down before any modeling.
Step 02 of 08
The shape, with its history
geometry.model · add hoops
The agent blocks out the barrel and adds the hoops. Every operation lands in a construction history, so any part can change later without starting over.
A clay render to judge the shape before any material.
Step 03 of 08
The right size, the first time
geometry.scale_to_spec · 0.70 m
The first block out came out 0.88 m tall. Glost scales it to the 0.70 m in the spec, so it lands in your engine at the size you asked for.
0.70 m tall, inside the spec box.
Step 04 of 08
Topology you can read
render.snapshot · wireframe
A wireframe render shows what you are shipping: 4,532 triangles in clean strips and rings, light enough for a game.
4,532 triangles, inside the 6,000 budget.
Step 05 of 08
UVs before paint
uv.unwrap · uv.pack orient
Every stave unwraps as one upright strip and every hoop as one band, all at one texel density, so a texture has somewhere clean to land.
A UV checker render shows any stretching, flips or seams.
Step 06 of 08
Oak and iron
material.set_texture · triplanar
Oak and iron go on as a triplanar material. For a generated texture, Glost projects several views onto the UVs instead and repairs the seams.
Checked in the lookdev modes before the final render.
Step 07 of 08
Checked under real light
render.snapshot · hybrid
A hybrid ray traced render checks the look on Glost's own Vulkan renderer, before anything leaves the app.
Rendered headless, so it runs the same on a server.
Step 08 of 08
Exported, then imported again
export.run · glb
The barrel leaves as a GLB with a profile for your engine. Glost imports the file again and checks it against the spec before it calls the job done.
verify.export passed on the file it wrote.
Every tool an agent can call is also a glost subcommand, so you can run any of these steps yourself.
04 Rigging
Every model in the hero
moves on a Glost rig.
Fifteen models, rigged and animated in Glost by an agent: joints at the real pivots, parts hung from them or skinned, linkages held by constraints, and clips that start and end at rest. Pick one, and drag the line to see its skeleton.
The model plays its clip. Left of the line it is drawn as in the hero; right of the line is a dev view, its parts coloured by the joint that moves them and its skeleton drawn over it. Space pauses and plays, the arrow keys turn the model, and the line moves with its own arrow keys.
Parts on a joint the clip movesStill partsBones the clip movesA rigid rig of two joints. The cask is a free joint on the centre of its bottom chime, limited to a 31° tilt, past which its centre of mass would pass over the rim; the bung is a slider, 20 mm along its bore. Its clip rolls the cask round on its rim.52 joints and 18 aim constraints, every part rigid. The wheels steer and spin, the springs shorten as the wheels rise, the doors and hatch swing on their real hinge lines, and each headlamp rises on a crank, rod and lever linkage that locks shut and open. The stand plays its headlamps, doors and wipers.Pixel art on a rig of four joints, 28 by 26 pixels, its body three voxels deep. The body joint at the middle of its base carries the hop and the squash and stretch, the eyes blink on their own joint, and the sprout and its leaves trail the bounce. Each voxel follows the part it was painted in.Voxel art on a rig of 19 joints, every part rigid. The door swings on its strap hinges and slams, and the cap, chimney, lantern, toadstools and flowers each shake on their own joint. Each voxel follows the joint of the surface it came from.13 joints: a turntable under the column, and the rest in the horsehair crest, the one skinned part, which lags each quarter turn, follows through and settles. The bronze never bends.32 joints on the real hinge lines, swept and with dihedral: the propeller and its blades, the ailerons, flaps, elevators and rudder with their trim tabs, the canopy, and the gear and its doors. Every part is rigid. The stand spins up the propeller, opens the canopy and lowers the flaps.Pixel art on a rig of nine joints, every part rigid. The hips carry the walk bob, the boots stay flat on their ankles, the plume trails the helmet, and the sword arm swings on the shoulder under the pauldron. Its clip is a march on the spot, then a wind up and a cut.Five joints: the lid on its hinge pins, from shut to 88° open, the hasp on its knuckle, and the body on a 6 mm slider for the hop when the lid lands. Its clip slams the lid and bursts it open.Voxel art on a rig of 11 joints. The lamp turns on the tower's axis and carries the beam along its own +Z, the tower and cottage doors swing, the sea foam rises, and the flag is skinned to its joints. The beams are drawn from the lamp's joint.102 joints from the thorax out, every segment rigid, as an exoskeleton is: antennae in six segments, mouthparts, legs from hip to foot, an abdomen of eleven segments and four wings. The stand plays it grooming.Pixel art on a rig of seven joints. The wings beat on their shoulders, the far one a moment behind, the body rises on each downstroke, and the tail is a chain of three joints that trails it and whips at the tip. Its clip lifts off on four beats, glides and lands.12 joints at the toy's real pivots: the legs, the arms on their shafts, four claw fingers, the head, the antenna and the wind up key. Seventeen parts, nothing skinned. Its clip is a wind up walk on the spot.Voxel art on a rig of five joints. The pad stays put, and the rocket is a free joint keyed through the rumble, the lift off, a quarter turn, the hover and the landing. The exhaust is drawn from the rocket's joint.24 joints: the chassis heaves over the bump, the body sways on its C springs, the fore carriage steers on the fifth wheel, and the doors, drop glasses and brake each have their own. Four meshes are skinned, so the springs flex. The stand plays it over a bump.Voxel art on a rig of 16 ball joints through the trunk and branches. The trunk is skinned to 15 of them, and the five foliage pads hang from their forks. Its clip is a gust from the front left: the pads sway in turn, and the tree settles.

Clips that fit your skeleton
Glost retargets animation between Mixamo, Rigify, Unreal, HumanIK and Character Creator skeletons: rest poses aligned, limb lengths compensated, feet kept planted. Joints are renamed to the convention your engine expects on export.
Generated characters next
For a generated character, Glost's auto rig finds landmarks on rendered views, fits a 70 joint reference skeleton and cuts fused fingers apart. It is built and tested on Glost's synthetic test characters; the learned keypoint and skeleton models it uses on real generated characters are still being wired in.
05 Into your engine
Every engine reads
a different file.
Unreal is Z up in centimeters and left handed, with DirectX normal maps. Unity is Y up in meters. Godot and Blender disagree with both. Guess wrong and the barrel arrives a hundred times too big, on its side, with its bumps lit from below.
| Target | Up axis | Units | Handedness | Normal maps |
|---|---|---|---|---|
| Unreal | Z up | cm | Left | DirectX |
| Unity HDRP and URP | Y up | m | Left | OpenGL |
| Godot | Y up | m | Right | OpenGL |
| Blender | Z up | m | Right | OpenGL |

FAQ
Before you ask.
Meshy and its peers generate a model. Glost finishes one. It can call Meshy, Tripo, Rodin or Hunyuan for the generation step, or run TRELLIS.2 on your own GPU, and then does the retopology, UVs, textures, rig and export under your agent, each step checked against your spec.
No. Glost covers the work between a generated shape and a file your engine accepts, driven by your agent. When you want to sculpt or animate by hand, take the asset to Blender: every export profile writes Blender's conventions, and a live Blender bridge is in progress.
In the desktop app on Linux: modeling, materials, rendering, texturing, export and the checks that import every export again. The quad remesher and the rigging pipeline are built and under active work; rigging still needs its learned keypoint models for real characters. There are no packaged releases yet.
JUMPHASH, a deterministic systems company and a member of the NVIDIA Inception program. Glost is proprietary software. Modeling, materials, rendering, rigging and export run on your own machine, and you pay a provider only if you choose a cloud step, after Glost asks.
Claude Code, Codex, Gemini CLI, Cursor, VS Code, Windsurf, Zed, Claude Desktop and Antigravity connect in one click. Any other MCP client can use the local endpoint over Streamable HTTP or stdio.
Glost renders with its own Vulkan and OpenGL renderer, so you need a GPU with a current Vulkan or OpenGL 4.6 driver. Local generation models run on NVIDIA, AMD or Apple silicon. Without a strong GPU, send generation steps to Replicate, OpenAI or Gemini after you approve the cost.
Not unless you say so. Projects live in a SQLite database and blob files on your machine. A cloud step asks before any file leaves, crash reports are never uploaded, and agents can never read your provider keys.
Every paid step shows an estimate before it runs. You set budgets per project and per session, and Glost records what the provider actually billed.
Every change is a command with its author recorded, so you can undo one step or the agent's whole run. You can also pause the agent, take over in the viewport and hand it back.
