bunpav vs Hi3D
bunpav vs Hi3D: portrait specialist vs. full game pipeline
Hi3D runs a dedicated portrait mode on its proprietary Sparc3D model, built specifically for high-fidelity facial geometry and natural hair — avatars, sculptures, digital doubles, and character heads. bunpav generates and auto-rigs full game-ready characters and props from a prompt or reference photo, but is still in private beta. Here's the honest breakdown.
quick answers
The short version
What is Hi3D actually specialized for?
Portraits and busts. Hi3D (formerly branded Hitem3D) runs a dedicated 'portrait mode' built on its proprietary Sparc3D model from developer Math Magic, tuned specifically for high-fidelity facial geometry and natural hair reconstruction — avatars, sculptures, digital doubles, and character heads.
Does bunpav have anything like Hi3D's portrait mode?
No. bunpav generates and auto-rigs full game-ready meshes from a prompt or reference photo, but it doesn't run a dedicated facial-geometry or hair-reconstruction pipeline the way Hi3D's Sparc3D model does. For a hero character's head/face detail specifically, Hi3D's specialization is a real advantage.
How does Hi3D's pricing compare to bunpav's?
Hi3D uses a credit system: Free (100 one-time credits), Pro (1,000 credits/month), Max (2,400 credits/month), Ultra (8,000 credits/month) — see Hi3D's current pricing page for the dollar amount per tier. bunpav sells prepaid packs instead: Starter $9/100, Studio $39/550, Pro $89/1,500 credits, no subscription.
Does Hi3D auto-rig characters like bunpav does?
Not documented as a bundled step — Hi3D's focus is generation quality for portraits/busts, not rigging. bunpav auto-rigs a humanoid or creature skeleton in the same generation pass, which matters if you need a moving character rather than a static bust or sculpture.

where bunpav wins
Auto-rig in the same pass
A generated character comes out with a humanoid or creature skeleton already attached — useful when you need a moving character, not just a static bust or portrait sculpture.
USDZ export included
Apple AR Quick Look support ships alongside GLB, FBX, OBJ, and STL — Hi3D's export list covers GLB, OBJ, FBX, and STL but not USDZ.
where Hi3D wins
Purpose-built for faces and hair
Hi3D's proprietary Sparc3D model runs a dedicated portrait mode for high-fidelity facial geometry and natural hair reconstruction — a level of specialization bunpav's general pipeline doesn't target.
Free retries and a live developer API
Up to 3 free retries per generation task without spending extra credits, plus a public API at platform.hi3d.ai — both available today, while bunpav is still gated behind a private-beta waitlist.
who should pick which
Match the tool to the job
Pick Hi3D if
You need the highest-fidelity facial geometry and hair for an avatar, sculpture, or digital-double head — a job its Sparc3D portrait mode is purpose-built for — and want a public developer API today.
Join the bunpav waitlist if
You need a full character or prop generated and auto-rigged in one pass, want USDZ export included, and can wait on beta access to open up.
faq
Questions, answered
What's the main difference between Hi3D and bunpav?
Hi3D specializes in portrait and bust generation — high-fidelity facial geometry and hair via its proprietary Sparc3D model — built for avatars, sculptures, digital doubles, and character heads. bunpav is a general text-or-photo-to-mesh pipeline with auto-rig built into the same generation pass, aimed at full game-ready characters and props rather than portrait busts specifically.
Is Hi3D good for full-body game characters, or just heads?
Hi3D's documented specialty is portrait/bust generation — faces and hair. It's not positioned as a full-body game-asset pipeline with rigging the way bunpav is. If you need a complete, riggable character rather than a head or bust, that's a meaningful scope difference to weigh.
What is Sparc3D, and who makes it?
Sparc3D is Hi3D's proprietary underlying model, developed by Math Magic. Hi3D was previously branded Hitem3D before adopting its current name.
How much does Hi3D actually cost per month?
Hi3D's tiers are credit-based — Free (100 one-time credits), Pro (1,000/month), Max (2,400/month), Ultra (8,000/month) — but exact USD pricing per tier wasn't confirmed here. Check Hi3D's current pricing page for dollar amounts before budgeting.
Can I sign up for bunpav today the way I can with Hi3D?
Not yet. bunpav is in private beta behind a waitlist at bunpav.com. Hi3D is publicly self-serve, including a developer API at platform.hi3d.ai — a real, current gap worth knowing before you plan a project timeline around bunpav.
