Luma AI 3D
Pros
- + Photoreal reconstruction quality with believable view-dependent detail when capture technique is good.
- + Open export path — .ply Gaussian splats and .luma files download freely and work in Unity, Unreal and three.js projects.
- + Free capture app on iOS (App Store, version 1.3.14 as of January 2026) with server-side processing — no local GPU needed.
- + Browser viewer, AR viewing, and website embeds make captures easy to share with non-technical stakeholders.
Cons
- - Product is legacy: the company has pivoted to video generation and no longer lists Interactive Scenes or Genie on its website.
- - Flythroughs was shut down January 1, 2026 with all cloud data deleted — the only hard evidence of what retirement looks like here.
- - Splat output only: no clean retopologized meshes, no UV workflows, unsuitable for game-ready geometry.
- - Reconstruction fails or degrades on reflective surfaces, thin structures, and dynamic scenes; the Android app is no longer listed.
Spline AI
Pros
- + Web export path is the shortest editor-to-published-scene distance I have measured for non-specialists.
- + Multiplayer browser editing with unlimited viewers on all plans worked without lock-step friction in my testing.
- + AI features (3D gen, textures, AI Agent) are embedded in the editor, so generated content lands as editable scene objects rather than standalone meshes.
- + Programmable surface — variables, APIs, webhooks, and MCP tool calls with limits that scale by plan.
Cons
- - Credit metering plus weekly media-generation caps mean AI-heavy workflows cost more than the headline seat price.
- - Not production-grade 3D: no deep rigging, simulation, or high-poly sculpting; heavy scenes get sluggish in the browser.
- - Free tier is a watermark-limited sandbox; code export and self-hosted export sit at Max or Enterprise.
- - Credit consumption rates per AI operation are under-documented.
