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 Collada (.dae) file in your browser

Collada is the XML scene format SketchUp writes and Blender still reads. Rendermio parses .dae in the browser, keeps the scene's objects as parts, and renders them on your machine.

How Rendermio reads Collada (DAE)

Accepted as .dae. Collada is XML, parsed in the page. Its scene tree becomes parts, one per mesh. A malformed file is reported plainly rather than rendering nothing — Collada exporters vary in quality, and SketchUp's in particular produces files that some tools reject. Materials are mostly set aside for the studio's own.

What comes through

Scene tree, each mesh a part
Normals and UVs where written
Units, when the file declares them

What does not

Collada materials, mostly — replaced by studio materials
Animation and cameras
Textures referenced as separate files

Exporting Collada (DAE) from your CAD program

From SketchUp, export with 'Triangulate all faces' on
Prefer glTF if your tool offers it — it is the format Collada was replaced by

Collada (DAE) files typically come from SketchUp, Blender, older Maya and 3ds Max pipelines, Google Earth-era models. 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

Can I render a SketchUp model in Rendermio?

Yes, by exporting it as Collada (.dae) or glTF from SketchUp — Rendermio does not read .skp directly. Turn on 'Triangulate all faces' in the export options for the cleanest result.

Is Collada still a good format?

It works, and Rendermio reads it. But it has been superseded by glTF, which is smaller, carries materials properly and is what web tools are built around. Use glTF where you have the choice.

My .dae will not open — what now?

Collada exporters are inconsistent. Re-export from the source program, or export glTF or OBJ instead; both are more reliable and read the same geometry.
