How do I turn a CAD file into product images?

Open the studio, drop in your file, and Rendermio converts it in the browser. Pick a material, choose one of the six Looks — each sets lighting, backdrop, pose and camera together — and export. A first image takes about a minute, and no 3D experience is needed.

Which file formats can I use?

STEP, IGES, BREP, Rhino 3DM, STL, OBJ, glTF, FBX, Collada, PLY, 3MF, AMF, 3DS, VRML, VTK, USDZ and Draco. STEP, IGES and BREP are converted with a real geometry kernel (OpenCascade compiled to WebAssembly) rather than an approximation, so curved surfaces stay curved.

Is my CAD file uploaded anywhere?

No. Conversion and rendering both happen on your own machine, using your GPU through WebGL. The file never leaves the browser and nothing about it is stored on a server — which is the point for anyone working on unreleased designs under NDA. Signing in creates an account for your plan only; it gives us no access to your work.

Can it render diamonds and gemstones properly?

Yes. The Traced renderer follows light through a stone's real facet geometry with dielectric Fresnel and dispersion, rather than faking sparkle with a texture. There are 40 cuts, sixteen of them real cut geometry down to a heart, and every stone in a piece can be tuned on its own.

Does it only do jewellery?

No. The same engine renders cars, furniture, buildings and household products. Jewellery gets the ray-traced gems and measured golds; everything else gets car paint, timber, leather, cloth, stone, glass and the industrial metals. Tell the studio what your file is and it dresses it accordingly.

Still images up to 8K, export packs sized for store listings, social and print, and a 360° turntable video as WebM or MP4. Cut-out PNGs carry a transparent background for compositing, and a contact sheet labels every frame in a pack.

The browser studio is free and ad-supported: all materials, cuts and looks, 8K images and turntable video. $4 a month removes the ads. Cloud path-traced rendering is planned as a further paid tier — email rendermiostudio@gmail.com to be told when it opens.

What do I need to run it?

A current desktop browser with WebGL 2 — Chrome, Edge, Firefox or Safari. Rendering uses your graphics card, so a faster GPU means faster exports, but a normal laptop handles the catalogue designs comfortably.

Mesh formats

Render a glTF or GLB file in your browser

glTF is the format built for the web, and it is the one Rendermio reads most completely: the scene, its materials and its compression all come through. Drop a .glb or .gltf in and it renders on your machine.

How Rendermio reads glTF / GLB

Accepted as .glb, .gltf. glTF is parsed natively, and Draco-compressed meshes are decoded in the browser. Unlike OBJ, its materials are physically based — the same model the studio uses — so a GLB's metallic and roughness values arrive as real materials rather than being replaced. You can still swap any part to a measured gold or a ray-traced stone; the difference is that you do not have to.

What comes through

The full scene graph, with every mesh as a part
PBR materials — base colour, metalness, roughness — as the file defines them
Draco-compressed geometry, decoded locally
Normals and UVs

What does not

Animations and cameras — a render is a still, or a turntable the studio drives itself
Textures referenced as separate files by a .gltf — use a .glb, which packs everything into one file, or the textures will not be found

Exporting glTF / GLB from your CAD program

Export .glb rather than .gltf so textures travel inside the file
Draco compression is fine and cuts file size dramatically — it is decoded on load
Give objects names in your tool; they become part names in the studio

glTF / GLB files typically come from Blender, Substance, Sketchfab downloads, Three.js and web pipelines, Fusion 360. Working in SolidWorks, Fusion, CATIA, Inventor or Creo? Their native files are not readable in a browser — here is what to export instead.

Then what happens

Once the file is in, the steps are the same for every format: tell the studio what the object is, and it dresses it — one click finds the stones in a ring and makes the rest gold. Pick a Look, which sets lighting, backdrop, pose and camera together. Export a listing pack up to 8K or a 360° turntable video. Everything runs on your own GPU; the file never leaves the page.

Questions

Does Rendermio keep the materials in my GLB?

Yes. glTF materials are physically based, the same model the studio renders with, so metalness and roughness come through as set. You can still replace any part with one of the studio's measured metals or gemstones, but the file's own materials render as-is.

Is a Draco-compressed glTF supported?

Yes. Draco geometry is decoded in the browser on load, so a compressed GLB renders identically to an uncompressed one and downloads far faster.

Should I export .gltf or .glb?

.glb. It packs the geometry, materials and textures into one file. A .gltf references its textures as separate files, and a single dropped file cannot bring those along.
