Omma AI Agent by Spline: A Review by a Spline Expert Designer with Project Showcases

On March 25, 2026, Spline officially released its AI agent, Omma.
From complex 3D scene generation such as liquid simulations and particle systems to building interactive websites and even mini-games, Omma is an incredibly powerful tool.
In this article, I’ll share my hands-on experience with Omma along with real project examples, from the perspective of a Spline Expert Designer.
What is the Omma AI Agent?
Omma is an AI agent developed by the team behind Spline, the interactive 3D design tool.
It can generate a wide range of content, including 3D models, interactive UI for websites, animations, and even realistic simulations such as fluid dynamics.

Built by the Interactive 3D Tool Spline
Omma is developed by the team behind Spline, known for its interactive 3D design capabilities.
While Spline focuses on creating interactive 3D experiences, Omma expands this further by enabling the generation of more complex 3D scenes that would be difficult to build manually within Spline alone.
What You Can Do with Omma AI
With Omma, you can generate 3D scenes using natural language prompts and continue refining them within the same environment.
The experience feels similar to what is often referred to as “vibe coding” — describing what you want and iterating quickly with AI.
Omma also supports code export, allowing you to integrate generated content into development environments when needed.
Can You Build Without Coding?
I’m a designer, and I don’t have a programming background beyond basic HTML and CSS.
Still, I rarely encountered any issues while using Omma.
When something needed fixing, I simply typed prompts like:
“this interaction is not working properly, please fix it,”
and Omma handled the rest by reading and updating the code automatically.
Another advantage is that scenes can be shared instantly via URL, so there’s no need to set up a local development environment.
Key Strengths: 3D + Interactivity in One Platform
All-in-One Workflow
Traditionally, creating 3D content, designing websites, and implementing interactivity required multiple tools.
With Omma, everything can be done within a single environment, significantly streamlining the workflow.
For example, I created a virtual shopping mall website where:
3D models
Website structure
Interactive navigation
were all generated within Omma.
It even supports multilingual setups including Japanese, English, Korean, and Chinese.
Evolution of AI 3D Generation (Inspect Mode)
One of the most impressive features in Omma is Inspect Mode.
In many AI 3D tools, generated models are merged into a single mesh, making them difficult to edit.
However, Omma generates models with properly separated meshes.
With Inspect Mode, you can select and highlight each part individually, making it much easier to understand and edit the structure.
This is a huge advantage for real production workflows.
This feels like a very “Spline” approach, coming from a team that builds browser-based 3D tools.
As a non-coder, I really appreciate how intuitive and easy this experience is.
Note: Inspect Mode seems to be in beta, as it doesn’t show up in some chats. Excited to see how it evolves.
Project Example: Matcap AI Generator
I created a Matcap AI Generator using Omma.
This tool allows you to import 3D models and generate custom Matcap textures using AI, all within a real-time 3D viewport.
You can load HDRI environments and preview lighting in real time, making it easy to test different lighting setups.
The tool detects the number of meshes and highlights the selected part, making it easier to work on specific areas.
It’s very easy to see which part of the model you’re selecting, and I’ve always wished more 3D tools had this kind of feature.
Being able to generate my own preferred workflow environment using Omma was a really enjoyable experience.
AI Matcap Generation
With AI, you can generate custom Matcap textures and preview them in real time.
The generated Matcap can be applied either to a selected mesh or to the entire model.
Using an AI agent like Omma to actually build another AI generator inside it was honestly quite mind-blowing.
The final Matcap textures can be exported as PNG images.
Omma 3D Export Button (Component)
Another component I created is a 3D Export Button.
By default, Omma mainly supports exporting via code or URL.
So I built a button that allows you to export generated 3D scenes as OBJ, GLB, and GLTF files.
In Omma, generated features can be saved as components.
By saving this export functionality as a component, you can easily reuse it in other chats and enable 3D export in different scenes.
Here’s an example where I added the export button to a physics-based LEGO-style 3D scene generated in Omma.
By reusing this as a component, you can export 3D scenes created in Omma in compatible formats such as GLB and import them into Spline.
Available for Remix in the Omma Community
Both of the scenes introduced above are available for remix in the Omma Community.
There is also a free plan available, so feel free to try it out.
Note: Login is required.

Can Omma Be Used in Real Workflows?
One of Omma’s biggest strengths is that it goes beyond simple 3D generation.
It allows you to build interactive experiences and web designs within a single workflow.
Not only can you export code, but even without reading or writing code, you can generate interactions, 3D animations, and models using natural language.
Because of this, Omma has the potential to become a shared environment where web designers, developers, 3D designers, UI designers, and even clients can collaborate using the same visual reference and prototype.
This approach strongly aligns with Spline’s philosophy:
“Design. Collaborate. Ship.”
as well as their vision to
“Supercharge your team to deliver production-ready interactive 2D & 3D experiences in an all-in-one platform.”
At the same time, as AI continues to reshape the creative landscape, I sometimes feel a sense of pressure being surrounded by increasingly powerful tools.
But rather than resisting it, I believe it’s important to continuously ask ourselves how we use AI, and where our own unique value lies as creators.
