Pixal3D is a new free image-to-3D AI model from Tencent.
The interesting part is source-image fidelity. It improves on Trellis.2 to better preserve the structure of the original image, so the generated 3D model stays much closer to the input instead of drifting away.
In this video, testing how accurately it follows the reference image.
Pretty cool example of where 3D AI can go beyond just generating standalone assets.
The creator used AI-generated 3D models and turned them into an interactive science app with a full UI, model viewer, labels, comparison tools, and extra info panels.

From concept to a playable procedural 3D platformer in Unreal Engine 5 in just 3 days, using 3D AI.
This was a solo project, and I think it’s a pretty strong showcase of how much game development is changing. The entry barrier is getting lower, and now one person can build a playable 3D prototype with custom characters, assets, and level pieces in less than a week.
Workflow:
It’s still a prototype, but the fact that this kind of playable 3D game can be built by one person in only a few days is honestly insane.

Pixal3D is a new Image-to-3D AI model that turns a single image into a high-fidelity 3D asset with detailed geometry and PBR textures.
The interesting part is its pixel-aligned approach. Instead of only loosely using image features, it back-projects them into 3D space, helping the generated model stay much closer to the original input image.
Highlights:
This feels closer to reconstruction-level fidelity, while still keeping the creative flexibility of 3D generation.

Interesting workflow showing how a single image can be pushed into a fully rigged character inside UE5 using 3D AI generation and MetaHuman tools.
Not a magic button workflow, but a solid look at how image-to-3D can become part of a real character pipeline for UE5.

Modly is an open-source desktop app for generating 3D models from images using local AI.
Why this is worth checking out:
This could be a really useful option for people who want to test image-to-3D workflows privately and freely, without getting trapped inside another “please buy more credits” ecosystem. Humanity briefly remembered software can just be software.
Try it at: https://github.com/RareSense/Nova3D Takes both text and image input. You'll need your own Gemini, Anthropic or Open AI key.

The problem it solves:
AI generators produce solid, monolithic 3D object that are great to look at but not practically super useful. Want to change the arm of a robot you generated? Re-generate the whole thing, lol.
About this tech:
It generates a Blender construction script, runs it server-side, does spatial validation, then exports a structured GLB (with the scene graph intact). Basically the output isn't only geometry. It's the procedure that built it, plus the asset itself.
In practice, this produces named parts, hierarchy preserved, material slots ready to go. And since there's a procedural script sitting in the middle, you can actually go in and edit the "kit of parts" afterwards instead of starting over.

Cascadeur is a standalone AI-assisted 3D animation tool, which means no cloud-token workflow just to pose, rig, or animate your models.
Cascadeur 2026.1 just added new tools aimed at faster quadruped animation workflows.
The update includes:
Quadruped animation is usually one of those tasks where every extra leg feels like a punishment from the software gods, so having AI-assisted posing, physics, and retargeting in one workflow is pretty interesting.
Could be useful for game devs, animators, creature artists, and anyone working with animals or fantasy creatures in 3D. It could also be very useful for bringing AI-generated 3D animal models to life, especially in faster game and creature workflows.
Cyanpuppets is showing an AI motion capture workflow for UE5.6 that can turn webcam footage or uploaded video into real-time 3D motion data.
Main points:
This kind of workflow is getting really interesting for indie game dev, previs, animation tests, VTubing, and fast character prototyping. It’s not replacing cleanup completely, because apparently suffering is still part of animation, but the speed is getting ridiculous.
Now imagine creating your own character from a single photo, then animating it with a plugin like this. You can get a pretty high-level character that is usable for games, and potentially build the whole thing by yourself in 2–3 days. That’s honestly insane.
This feels like a pretty huge step for AI-assisted game development.
Unity AI is now available in open beta, bringing AI tools directly inside the Unity Editor instead of forcing developers to constantly jump between external tools, scripts, plugins, and random workflow hacks like it’s some kind of productivity obstacle course.
What it is:
A built-in AI system for Unity 6 that helps with game dev tasks, asset generation, editor automation, debugging, planning, and faster prototyping.
Key features:
The biggest thing here is not just “AI can generate assets.” The more interesting part is that AI is moving directly into the actual game engine pipeline.
For indie devs, technical artists, prototypers, and small teams, this could be very useful for speeding up early development, blocking out scenes, testing ideas, creating placeholder content, and automating boring editor work.
I’m still curious how good the generated 3D assets will be in terms of topology, optimization, UVs, and real production use. But as an assistant for faster Unity workflows and game prototyping, this looks like a serious step forward.

I tested the retopology in the new Rodin Gen 2.5, and honestly, I was surprised by the result.
The original mesh had almost 2 million polygons and pretty messy topology. Rodin managed to optimize it down to around 3,000 faces while keeping the overall shape readable and producing a much cleaner quad-based mesh.
It is obviously not a perfect final production mesh, but as a starting point, this is actually very useful. You can treat it almost like a clean base mesh or blockout and continue modeling, refining, baking, or rebuilding details from there.
The PBR textures also came out pretty decent, which makes the result feel more complete instead of just being a simplified mesh with no usable material information.
Stats:
A pretty cool example of how fast AI-assisted game prototyping is getting.
built this arcade-style fighting game prototype in just 2 days using a mix of UnityAI, Codex, and Claude.
Workflow details:
The result is still rough, but for a 48-hour no-code / AI-assisted prototype, this is honestly impressive. We’re getting closer to the point where one person can quickly test full game ideas instead of spending weeks just getting the basic prototype working.
Showcase of how AI can be used inside a real 3D workflow to speed up character production and reduce development time.
Workflow:
Total time: 8h
Scene size: around 30,000–35,000 faces.

Most 3D AI tools are focused on generating meshes, but materials are still one of the biggest bottlenecks. A model can look decent in a preview, but if the PBR data is weak, it quickly falls apart in real-time engines or under different lighting.
This new Image-to-Material model focuses on generating proper PBR maps for 3D assets.
The workflow is basically:
For AI-generated 3D assets, this could be a very useful missing piece. Mesh generation is improving fast, but clean materials, proper maps and relightable surfaces are still a huge problem.
If tools like this keep improving, AI 3D workflows could move closer to actual production-ready assets instead of just nice-looking demo renders.
Autodesk Flow Studio now seems to be pushing toward a full AI character workflow:
The interesting part is that Autodesk is not just showing “text/image to 3D”, but trying to connect character generation, rigging, and animation into one workflow.
If this works well in practice, it could be pretty useful for indie game devs, previs, stylized characters, and quick animation prototyping.
Basically: generate → rig → animate.

This is a Blender-based AI 3D editor workflow where the whole environment pipeline happens inside one workspace.
It looks like a modified Blender fork with an AI agent built directly into the editor, so instead of jumping between separate tools, the workflow stays in one place.
The pipeline shown:
The tool is called Mixar, and according to the creator, it is a Blender fork. The built-in agent uses Claude and Gemini, while the image-to-3D side can use models like Hunyuan, Rodin, Tripo, and SAM3D.
This looks like a practical direction for 3D AI tools: not just generating a single mesh, but connecting the full production workflow around it.
This workflow shows how a 2D image can be turned into a rigged MetaHuman-style character for Unreal Engine, using an AI-generated head as the starting point.
The pipeline is roughly:
Pretty cool example of how AI-generated character heads can be pushed further into an actual game-ready character workflow instead of stopping at just a concept image.

A cool example of a web-coded character selection menu built with AI-generated 3D assets.
The workflow is basically:
The final assets were compressed heavily for web, with each GLB reportedly landing around 400–800 KB after optimization.
Pretty nice showcase of where AI-generated 3D assets can fit into lightweight game-like web experiences.
