What's new in Spline

AI agent & generation

• MCP access - External agents (Claude Code, Cursor, etc.) drive the 3D editor through MCP tools.

• AI Chat agent - Generate or edit 3d scenes using AI agents within the 3D editor. Generated scenes are fully editable.

• Deep AI scene editing - The agent can create and edit everything: objects, materials, lights, cameras, booleans, particles, cloners, paths, sky, variables, and full interactivity (events, tweens, states), as well as custom code-driven interactions.

• AI scene composition - The agent can lay out structured, multi-object scenes, use procedural generators, and make changes scene-wide.

• Preview tab - A new play mode for the 3d scene and any html or code interaction.

• Code tab - Spline now supports HTML/JS code that can access to the scene's data and modify it, or create new procedural data during runtime. Agent generates HTML/JS layered over the 3d canvas; motion, interactivity or games can be code-driven by default.

• Version history - Every AI prompt saves a Version History entry.

• AI image & 3D AI gen tools - Chat generates textures/images and 3D models in the background while continuing work.

Rendering & engine

• WebGPU renderer - New TSL-based WebGPU backend by the default, WebGL as fallback.

• PBR material support - Image-based lighting (IBL), new map channels, BRDF, glTF interchange, and an HDR color pipeline.

• Screen-space reflections - New reflection layer supporting SSR (WebGPU only), plus a Surface Shape/Mirror toggle. Mirror mode enables true planar mirror reflections with optional blur.

• Physical Sky - Procedural sky with its own dome light, Light Intensity dial.

• HDRi Sky - Support for .hdr as sky box with IBL, Show-BG switch keeping lighting only.

• Height fog - Realistic camera-angle-dependent fog with Height and Both modes alongside classic depth fog.

• Shape blend overhaul - New 512³ resolution, faster compute, ability to use any mesh as a shape blend.

• Dust material layer - Procedural dust/snow accumulation shading on upward-facing surfaces.

• Hair System - GPU accelerated hair strand simulation for growing hair from scalp shapes or any mesh, with lighting, shadows, wind, clumping.

• Faster boolean operations - Roughly 4× faster overall, fixing subdiv baking and degenerate-geometry cases.

• GPU instancing - Cloner now uses GPU mesh instancing; shared geometry+material pairs can get auto-collapsed into single instanced draws.

• Vertex-color material layer - New material layer that imports and renders glTF per-vertex colors.

• Physics upgrade - Improved physical character-controller contacts; dragged rigid bodies now drive kinematics properly.

• Export size optimization - Smaller base runtime size, with adaptable size based on features, improving loading times.

• Editor chrome redesign - Redesigned top nav (tabs left, toolbar centered, Preview = Play), Preview/Edit/Code stage tabs, refreshed light/dark themes with monochrome accent.

• Performance overhaul - Idle-leak fixes, shadow caching, faster AO, faster selection, batched subdiv WASM, optimized path geometry, optimized soft shadows, faster tessellation.

Modeling & tools

• Bevel/Chamfer tool - New mesh-editing bevel with round mode, segments control, floating toolbar with live rebuild, and smarter edge-loop selection.

• Texture projection axes - X/Y/Z axis control for cylindrical and spherical texture projection.

• Camera UX - Smooth perspective↔orthographic transitions.

• Outliner type filter - Filter the outliner by object type.

• Sculpt & mesh upgrades - Brush symmetry for sculpting plus UV support for sculpted and editable meshes.

• New-file defaults refresh - Fresh files open in perspective with an offset camera, HDRi sky, soft shadows, darker default colors, no seed rectangle.

• Import fidelity - GLB/glTF imports keep faithful PBR materials, intern textures as shared assets, accept separated assets and .hdr/.exr, land normalized to height 500.

Dashboard & app

• Home redesign - New Home with a prompt hero, later a recents list plus bottom composer; prompts hand off directly into the editors' chat.

• Workspace search - Sidebar-invoked modal searching files across the workspace.

• Files & templates redesign - Reworked files list view, templates page with inline tabs, sidebar My-Files folders with paging and newest-first ordering.

• New pricing plans - Restructured to Hobby/Pro/Max with per-plan credit selection, replacing the AI addon.

Deprecated

• AI Style Transfer is now deprecated.

• UI Scenes is deprecated in favor of the new html approach for UI generation. Files with existing UI scenes will load fine (and faster due to Hana’s replacing old UI renderer).

• Frame Mode is deprecated, however the in-editor frame overlay still work as before.

• Playmode is now Preview Mode.

Multi-Agent Workflow: Omma runs code, image, and 3D generation agents simultaneously to build complex scenes and apps in seconds.

• Beyond Static Pages: Create interactive web apps and games powered by WebGPU, including physics-based simulations and real-time reflections.

• Real Data Integration: Connect your projects to the real world with support for CSV, JSON, and DOC files, as well as GLB/GLTF 3D models.

• Community Remixing: Don’t start from scratch—browse the community gallery to fork and customize existing projects.

• Instant Deployment: Go from a prompt to a live URL with production-ready hosting and custom domain support.

• Advanced Web Tech: Built-in support for industry standards like Three.js, Tailwind CSS, and React Three Fiber.

• Parallel Iteration: Generate multiple variations of an idea at once, pick the best result, and keep building.

What’s the first thing you’re planning to describe and build?
