OBJ, FBX, and GLB reference models from independent creators — ready to import into Gravity Sketch for product concept, automotive styling, footwear design, and character exploration in VR.
Gravity Sketch is a professional VR and desktop 3D design tool developed by Logitech Design. It lets designers sketch, sculpt, and model in immersive virtual reality using motion controllers — a fundamentally different workflow to mouse-and-keyboard 3D software. Designers use it for concept exploration, ideation, and visual communication of product ideas before committing to precise CAD geometry.
Gravity Sketch is widely used in automotive styling, footwear design, consumer product design, industrial design, and character concept art. It runs on Meta Quest headsets, PC VR (SteamVR), and has a desktop companion app. Its workflow integrates with Alias, VRED, Maya, Blender, and ZBrush via OBJ and FBX interchange — designers sketch a concept in VR and hand off to a technical surfacer or character artist for production geometry.
Import a vehicle body shell or competing car model as OBJ reference to sketch proportions over in VR. Compare silhouettes and surfacing ideas in 1:1 scale without committing to technical geometry.
Import a shoe last, foot form, or anatomical foot mesh as a base. Sketch the upper, outsole, and toe box design directly in VR at true scale — then export and surface in technical footwear software.
Import a human body scan, anatomy reference, or base mesh to sketch character designs over in VR. Block out costume, armour, or creature silhouette ideas in real-world proportions.
Import a competitor product or similar device to sketch design variations around. Explore grip geometry, form language, and proportional changes before building precision CAD.
Clean geometry import with optional MTL material data. Most universally supported format for reference meshes. Predictable import with no rigging complexity.
Browse OBJ →Imports rig and bone data — useful for poseable character or creature reference in VR. Supports animation playback in Gravity Sketch for motion reference.
Browse FBX →Imports PBR materials and textures, giving realistic surface appearance in the VR reference model. Useful when material differentiation is important for the design process.
Browse GLB →Gravity Sketch renders in real-time VR at 72–90fps. High-polygon reference meshes reduce frame rate and cause VR discomfort. Use these guidelines when selecting reference models:
| Reference Type | Recommended Poly Count | Notes |
|---|---|---|
| Vehicle body shell | Under 100k triangles | Full car silhouette at mid-poly is enough for proportion sketching |
| Human body / anatomy | Under 80k triangles | Face and extremity detail not needed for product-scale reference |
| Shoe last / foot form | Under 30k triangles | Simple geometry; very low poly is fine for footwear proportion |
| Creature / character | Under 150k triangles | Balance detail vs. VR render budget; decimate if needed |
| Photogrammetry scan | Decimate first | Scans often 5M+ triangles — reduce to 200k before importing |
Inspect every reference mesh in a browser 3D viewer — check scale, topology, and proportional accuracy before buying. No surprise geometry in your VR session.
One payment. Use the reference model in client projects, professional design work, and commercial deliverables without subscription renewal.
Every download is invisibly watermarked. If a file is redistributed without authorization, the creator can trace exactly which download it came from.
Gravity Sketch supports importing OBJ (.obj), FBX (.fbx), and GLB/GLTF (.glb, .gltf) files. OBJ is the most universally reliable format for reference mesh import — it brings in clean geometry without rigging complexity. FBX works well if you need to bring in a rigged character or vehicle with bones for poseable reference. GLB/GLTF imports PBR material data, which is useful if you want a realistic reference model that maintains its colour and texture in the VR environment. For export, Gravity Sketch can output OBJ, FBX, GLB, and STL to bring your sketched designs into other software.
Gravity Sketch's core use case is concept sketching and design exploration in VR — not finished asset creation. Designers import reference meshes to: sketch proportions and silhouettes over existing geometry (a car body reference, a shoe last, a human body scan); quickly establish scale in the VR workspace; use an existing product as an overlay target for redesign concepts; import a client's existing product in OBJ format to design accessories, packaging, or derivative forms around it. The reference model stays in the scene as a semi-transparent ghost while the designer sculpts and sketches the new concept on top.
The most in-demand reference meshes for Gravity Sketch workflows are: human body and anatomy references (full body, hands, head/skull) for character and product design scale; vehicle body shells (car, motorcycle, truck) for automotive concept ideation; footwear lasts and foot forms for shoe design; ergonomic grips and hand-hold forms; animal and creature anatomy for character concept; furniture forms for interior concept work; and electronic product shells (phone, laptop, headphone) for UI hardware design exploration. Realistic proportional base meshes at medium polygon count work best.
Gravity Sketch runs in real-time VR at 72-90fps — high polygon counts directly impact rendering performance and VR comfort. For reference models: under 100,000 triangles is ideal and imports without any performance impact; 100k–500k triangles still works but may slow scene performance in complex multi-object scenes; above 500,000 triangles is not recommended for VR reference work. A mid-poly model (50k–150k triangles) of a human figure or vehicle body shell gives accurate proportions without taxing the VR renderer. Avoid photorealistic photogrammetry scans (often 5M+ triangles) — decimate them first in Meshmixer or ZRemesh in ZBrush before importing.
Yes. Proofly models carry a permanent commercial license. In a design workflow, using a reference model to proportion and design a new product in Gravity Sketch is fully covered — the commercial license applies to the reference use. The resulting design you create in Gravity Sketch is your original work. The restriction is redistribution of the raw reference file itself — you can use it as a design aid, but not re-sell it as a 3D asset. Permanent license means it never expires regardless of whether you maintain a Proofly subscription or account.
Yes. Gravity Sketch exports OBJ, FBX, GLB, and STL — all popular formats on Proofly. If you design product concepts, footwear, automotive parts, characters, or furniture forms in Gravity Sketch and want to sell the resulting meshes, you can export and list them on Proofly. Proofly charges 0% seller commission — buyers pay a $1 platform fee, you keep 100% of your price. Every download is invisibly watermarked with HiddenMark so you can trace unauthorized redistribution of your original designs.
