When is KeyShot the better choice?
- You render many kinds of products, not only jewellery, and want one tool for all of them.
- You need deep scene building: many objects, labels, animation beyond a turntable, or custom studios.
- Your team already has KeyShot plug-ins in its CAD workflow and network rendering.
When is Jart a better fit than KeyShot?
- You want to try a render today without a desktop install or an annual subscription.
- 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 KeyShot?
The two also work side by side: KeyShot for campaign images, Jart for the everyday: quick renders of every design, a 3D link the client can turn, and the weight and stones for the quote.
