Spline V2

Product Introduction

1. Definition: Spline V2 is a web-based, collaborative 3D design and interactive experience platform. It is a complete rebuild of the original Spline editor, positioning itself as a real-time 3D design tool for the agentic era, enabling users to create, animate, and publish interactive 3D content directly in the browser.
2. Core Value Proposition: Spline V2 exists to democratize the creation of production-ready, interactive 3D and 2D experiences by providing a unified, web-based platform that integrates AI-assisted design, real-time collaboration, and multi-platform deployment. Its primary value is enabling designers and teams to build complex 3D visuals and interactive prototypes without requiring deep expertise in traditional 3D modeling software or game engines.

Main Features

1. AI Agent Mode and Spline MCP: This feature introduces an AI co-pilot directly within the 3D workspace. The AI agent can assist with tasks like generating 3D objects from text prompts, applying materials, setting up animations, and writing custom logic via the Spline Model Context Protocol (MCP), which connects the AI to the scene's internal state and functions.
2. WebGPU-Powered Engine: The core 3D rendering engine has been rebuilt to utilize WebGPU, the next-generation web graphics API. This provides significantly faster rendering performance, more efficient GPU compute access, and enables advanced real-time graphics features like Physically Based Rendering (PBR) and High Dynamic Range (HDR) workflows directly in the browser.
3. Custom Code/Scripting: Spline V2 allows for the injection of custom JavaScript code to create complex interactivity, logic, and data integrations. This can be used to control animations with events, connect to external APIs and webhooks, manipulate variables in real-time, and build game-like mechanics without leaving the design environment.
4. PBR/HDR Material Workflows: The platform supports advanced material creation through a layer-based system, including full Physically Based Rendering (PBR) with metallic-roughness workflows and support for High Dynamic Range (HDR) environments and textures. This allows for the creation of photorealistic materials and lighting.
5. Real-Time Collaboration & Multi-Platform Export: Multiple users can edit a 3D scene simultaneously. Finished projects can be exported as embeddable code snippets for the web (React, Next.js, vanilla HTML/JS) or as native viewers for iOS (Swift) and Android (Kotlin), enabling seamless integration into websites, apps, and digital products.

Problems Solved

1. Pain Point: The high technical barrier and workflow fragmentation in creating interactive 3D content. Traditionally, this requires separate software for 3D modeling (e.g., Blender, Maya), another for real-time rendering/game logic (e.g., Unity, Unreal), and developer intervention for web or app integration.
2. Target Audience: UI/UX designers, product designers, brand designers, marketing teams, indie game developers, and front-end developers who need to incorporate interactive 3D elements into digital products but lack extensive 3D engineering resources.
3. Use Cases: Creating interactive 3D product configurators and mockups for e-commerce; designing animated 3D logos and brand assets for marketing websites; building gamified onboarding experiences and educational simulations; prototyping interactive UI elements and spatial interfaces; developing lightweight 3D animations for web and mobile apps.

Unique Advantages

1. Differentiation: Unlike traditional 3D suites (Blender, Cinema 4D) focused on offline rendering or complex game engines (Unity, Unreal), Spline V2 is a purpose-built, web-native tool that prioritizes designer-friendly workflows, real-time collaboration, and direct publishing to the web. It bridges the gap between design and development for 3D interactivity.
2. Key Innovation: The integration of an AI Agent Mode directly into the 3D design process is a significant innovation. By combining a WebGPU-powered engine with an AI co-pilot capable of understanding and manipulating the 3D scene graph, Spline V2 reduces iterative friction and opens up 3D design to a broader, less technical audience.

Frequently Asked Questions (FAQ)

1. Is Spline V2 free to use? Yes, Spline V2 offers a robust free plan for individual users, which includes core 3D modeling, animation, and publishing features. Paid plans (Pro, Team) unlock advanced collaboration, higher-resolution exports, premium assets, and commercial licensing.
2. Can I use Spline for game development? While not a full replacement for game engines like Unity, Spline V2 is excellent for creating interactive 3D experiences, prototypes, and lightweight web-based games. Its event system, physics, particle systems, and custom scripting support allow for the creation of complex interactive mechanics.
3. How does Spline V2's AI Agent work? The AI Agent acts as a co-pilot within the editor. You can issue natural language commands (e.g., "add a glowing material to this sphere," "create a walking animation for this character") and the AI will attempt to execute them by manipulating the scene, writing code snippets, or applying assets from its library.
4. What are the system requirements for Spline V2? As a web-based application, the primary requirement is a modern browser (Chrome, Edge, Safari, Firefox) that supports WebGPU. Spline also offers downloadable desktop apps for macOS and Windows for improved performance and offline access.
5. How do I embed a Spline scene into my website? You can publish any scene from Spline V2 and receive an embed code snippet. This typically involves adding a <script> tag to import the Spline viewer library and a <spline-viewer> custom HTML element pointing to your scene's URL, which can be integrated into platforms like Webflow, Framer, React, or vanilla HTML.
