Introducing Spline V2
August 21, 2026
Introducing Spline V2, a complete rebuild of our 3d editor for the agentic era.
Changes
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.
