| Rendering | Path tracing on your own graphics card in the browser (WebGPU), with refraction and colour fire in stones; a fast Interactive view for setting up. 51 gemstones and 19 metals ready to use. | Cycles, a path tracer, and EEVEE, a real-time engine. GPU rendering on NVIDIA (CUDA, OptiX), AMD (HIP), Intel (oneAPI) and Apple (Metal). Gem and metal materials, lighting and studio are built by you or with add-ons. |

When is Blender the better choice?
- You want full control over every light, material and node, and do not mind building it yourself.
- You also model, sculpt or animate, or render things other than jewellery.
- Cost decides: Blender is free for any use.
When is Jart a better fit than Blender?
- You want gem and metal materials, studio lighting and looks ready on day one rather than built from scratch.
- Nothing to install. Open a 3DM, GLB, STL or OBJ in a browser, on a Mac, a PC or an iPad, and render it there.
- Your own graphics card, in the browser. Render path-traces on the computer you are using, so there is no render farm or upload, and no plan limits how many renders you make.
- Made for jewellery. Metals by alloy and stones by name, set from your object names by Auto assign, with refraction and colour fire in Render.
- Clients see the piece, not only pictures. Share links open in 3D with no account, and an approval link (Pro) lets a client approve a version by name.
- Facts and casting checks. Design Facts weighs the metal in each alloy, counts the stones with their carat and reads the ring size; the cast check (Pro) looks at wall thickness, prongs and seats.
- A record from approval to the shop. An approval keeps a SHA-256 fingerprint of the exact files; the caster pack carries the metal STL, the facts and a fingerprint of every file; a Piece Passport page records the finished piece; Copy for Shopify puts the facts on a product page (Pro).
- An API and MCP server. Scripts and AI assistants measure a file's metal weight, stones, ring size and cast check, and check whether it is the version a client approved (Developers, Pro).
Can you use Jart alongside Blender?
Blender is a fine place to build a one-off campaign scene. For the daily round of renders, client previews and approvals, Jart takes the CAD file as it is and needs no setup per design.
