Sloyd Review: Parametric AI 3D for Game Props

What is distinctive: parametric, not just generative

Sloyd’s homepage describes “AI-guided parametric templates” and hundreds of them, plus text to 3D, image to 3D, topology control (“Set target polygon counts, and use quads”), style presets and custom styles, AI image editing, AI texturing, and “Automatically add rigging with one click.” Plugins for Unity, Unreal and Blender are listed on Plus and Pro; homepage logos also show Godot, Maya and Roblox.

For a developer the argument is output that survives the next step. Our reasoning is that a parametric prop has a known structure, so its polycount and UV layout may be more predictable than a generated mesh; Sloyd’s pages we read do not state that, and we found no independent output review of Sloyd. How to compare game props sets out the checks; we have not run them on Sloyd. See also LODs for AI models if you need to generate variants.

Who should use it and who should skip it

• Use if: you are building a game with many similar props (a stylized interior kit, a weapon set) and want sliders instead of re-rolling prompts, and you are willing to pay for Plus.
• Skip if: you need organic characters or creatures, which we expect templates to suit less well (inference, not documented), or you plan to sell 3D prints without negotiating a license.
• Not for: anyone who needs to ship from the free tier.

Pricing and credits

As of November 2026, per sloyd.ai/pricing: Guest $0; Plus $15 a month ($12.50 a month, $150 billed yearly); Pro $50 a month ($41.67, $500 yearly). Sloyd’s billing toggle says “Annual save 20%”, but its plan cards say “2 months free”, and the prices match the cards: $150 a year against $180 paid monthly saves $30, and $500 against $600 saves $100, which is 16.67% on both plans. Monthly billing does cost 20% more than the annual rate, so the label holds only in that direction. Budget on the dollar figures. Monthly AI credits: none on Guest, 50 on Plus, 350 on Pro. Top-ups are $12 for 100 credits and work as a reserve: they carry over from month to month, while unused monthly credits do not and are spent first.

Credit costs listed: split to parts 20; image to scene 30; text to animation 30; video to animation 30; multi-image to 3D 20; ultra-high generation (500K triangles) 5; LLM-guided 3D creation 10. Text-to-3D and image-to-3D are listed as unlimited on Plus and Pro, with two parallel generations on Plus and five on Pro, and a priority queue on Pro. The pricing page adds that “fair-use limits and queue priority still apply” to those unlimited items, and does not publish the limits. Guest is listed at one AI 3D generation per day on the pricing page as read this pass; earlier reads listed one text-to-3D, one image-to-3D and one AI skybox a day, so confirm on the page. The API is billed separately on prepaid credits. Payments are “generally non-refundable”; mistaken-charge requests are accepted within 14 days.

Arithmetic: Plus’s 50 credits cover only about two multi-image generations at 20 each plus change, so credits matter for the premium operations, not basic generation. That is a reason to read what is metered before choosing Plus over Pro. Compare it to credit-only vendors such as Meshy.

License: the 3D printing clause

Pricing page by plan: Guest is personal-use only; Plus allows commercial use without marketplace resale; Pro allows commercial use and reselling; AI training with the models is not allowed on Guest or Plus and “Contact us” on Pro. The Terms of Use (updated 16 February 2026) say: “You have a non-exclusive, perpetual, worldwide right to use models from the web-app within your creations” and “Personal, non-commercial and commercial use are permitted.” Note the wording: a right to use, not ownership. The same Terms say “3D printing is allowed for personal use only,” with commercial printing needing a custom license from [email protected], and marketplace resale limited to Pro.

A search summary of Sloyd’s FAQ says Plus and Pro can sell prints royalty-free, contradicting the Terms; we did not fetch that page, and the Terms govern. For a hobbyist planning to sell miniatures, that is the deciding fact: get written confirmation. See selling 3D prints of AI models and selling AI models on marketplaces. Community library models are reported as CC BY 4.0 (search summary, not fetched). This is not legal advice.

Formats and print output

The pricing page lists Guest exports as “Standard (GLB, OBJ)” for community models only and “Unlimited exports” for Plus and Pro, and the homepage mentions manifold STL or OBJ with a stable base for printing. Sloyd’s documentation fills in more. Its export page says both GLB and FBX exports include textures; GLB “works in any software that can import GLB” (Unity needs the free glTFast package), while FBX works directly in Blender and Unreal and, for Unity and 3ds Max, “need[s] the texture as a separate file,” which the docs say you can produce by round-tripping through Blender. If a GLB shows no texture after import, the docs say to enable texture view. A vendor blog post dated June 3, 2025 recommends GLB for games, STL for printing (surface geometry only, no color) and OBJ for exchange with DCC tools, and does not mention FBX. A search summary of Sloyd’s template-editor docs said only GLB/GLTF and OBJ are supported, with FBX “coming,” but that page returned “Page Not Found” when fetched, so the FBX answer is: documented as working on the export page, absent from the blog, unconfirmed per plan. The API documentation mentions GLB as its output.

For print use, Sloyd’s troubleshooting page says that if a model shows errors in print software, you should use a “repair model” function or a free online repair tool, which is an admission that exported meshes can need repair. Whether the STL export is watertight is not documented. See AI model generators for printing and, for what slicers do with a bad mesh, fixing an AI model for the slicer.

What the API leaves out

A scripted pipeline can generate from text, one image or several images through Sloyd’s API, and its documentation also covers text to image, image edit, uploading an external 3D model, retexture and split to parts. Plan for asynchronous jobs: per the docs, a POST returns a job ID in under a second, and your code then has to poll until the job reports success or error. Two items the homepage presents as features are not in that API: spritesheet generation and rigging/animation are marked coming soon, and the docs say the endpoints are not yet enabled for public API keys. The homepage promise of one-click rigging therefore applies to the web app, not to a scripted pipeline. Request parameters, polycount and LOD options, rate limits and retention are not covered in what we read.
