GPT-6 changes 3D modeling forever. It works inside Blender completely autonomously, like an artist: gathers reference photos on its own, builds the scene, renders test frames, checks them against the references, then fixes what's off. When the scene holds up, it ships it to Unreal Engine 5 as a...

The Palace of Fine Arts in San Francisco, rebuilt by Astra in Blender. It found hundreds of photos of the real building, rendered intermediate frames, and compared them against the references until the scene matched. 1.5x speed.

A house modeled in Blender from a design drawing, then imported into Unreal Engine 5 as an explorable scene. Game studio Playco ran Astra on a single greybox and got three playable prototypes, with about half the manual fixes of their usual pipeline.

The kart racer from the launch page, playable right in the browser. More from day one: a voxel London shifting between medieval, Tudor and modern eras (@chetaslua), and Pietro Schirano's underwater exploration game built from pictures, with sound and gameplay.

holy shit imagine shelling out for a 3d artist and the intern just installs gpt-6 instead blender + unreal pipeline in one prompt is wild though. the whole "checks its own renders and fixes them" part is what actually scares me

AI bros have been claiming every single ChatGPT/Claude update changes 3D modeling forever since GPT-3.

the 'checks against references, then fixes' loop is the part i'd want to see uncut. does it converge in 2-3 passes or is it still drifting at iteration 8?

Can someone explain how it works? Can I input an image into GPT-6 and get the model? Does it work on character model?

The 'render → check → fix' loop is the part that actually matters here. Most 'autonomous 3D' demos skip the second pass and ship whatever the first prompt gives back. If Astra closes that loop without human QA, indie art-pipelines just collapsed into one afternoon.

I’m team Grok, but I will say, this is quite the accomplishment, and it is a testament to the power of world modeling. Manipulating an environment in true three dimensions to match a desired outcome is a big step.

I kept seeing #GPT-6 Astra modelling results on here and got curious enough to build the thing myself: an agentic pipeline that turns a plain RGB video into 3D assets. The living room for robots MIT CSAIL. Input: one handheld phone walkthrough of our lab kitchen (~20s). Nothing else — no depth sensor, no CAD, no asset library. ~1 day (I actually slept overnight), including human-in-the-loop. Live: It is still not perfect — thin and shiny things are still weak, a few objects are drafts, the room shell needs another pass. The loop, roughly: - Monocular video → metric scan (ViPE): camera poses + depth. This is the measuring instrument, not the output. - GPT-6 lists what should exist as separate objects, then open-vocabulary detection + tracking gives per-object masks; each object is fused and measured in metres. - For every asset, GPT-6 works in its own sandbox with tools: it writes the object as a program in a small Blender DSL (closed solids, PBR colours, hinges/drawers), builds it, renders it over the original video frames, compares it with the scan points in 3D, and iterates. - A separate GPT-6 session is the verifier — it can render the model on any frame it wants and must justify every complaint with a frame. The modeller never grades its own work. - A completeness pass renders the whole modelled scene from the video's own cameras, puts it next to the real frames, and says what's still missing. What the detector keeps missing (a row of identical cabinets) gets placed geometrically instead. - Out comes MJCF/URDF with joints. Now, adding simulation to this env.

I got this custom scorpion rigged, animated and running in my game in one full day with AI. GPT-6 built the entire rig. My part was preparing the model and motion references, then giving feedback. After trying a few approaches, I found a workflow that worked: 1. Give it a model that makes sense. I generated the model with Tripo P2.0, then cleaned it up myself. Low-poly, optimized, split into logical parts. I think that preparation mattered a lot. GPT-6 works on the mesh through code. A manageable vertex count and sensible parts give it a clearer starting point for bone placement and skinning. 2. Show it the movement you want. I took a reference image of the character and used Seedance to generate side-view animation videos. I decided which animations the game needed and selected the takes with the movements I liked. Then I gave GPT-6 the model, the videos and that animation list. There was no existing rig to start from. 3. Compare the animation frame by frame. This was the idea I wanted to test: ask GPT-6 to compare its Blender animation against the reference video frame by frame, from the same view. That gave it concrete poses and timing to work toward. I could point to where the feet should be planted or when the tail should strike. 4. Expect to give feedback. A generated run can look like hopping. An attack can start with a jump you never wanted. Choosing the references matters, and a side view still leaves depth and hidden legs to figure out. It took several iterations. I explained what looked wrong and how I wanted it to move, and GPT-6 kept refining the animation. Once the walk worked, I also had it create left and right strafe animations procedurally from that walk. Those didn't need their own reference videos. By the end of the day, the creature was in Unity. I've recorded the full workflow, including the Blender setup and feedback process:
