Question 1

Is HeyGema a KeyShot alternative for jewelry?

Accepted Answer

For client proposals, approvals and quick versions in different metals and stones, yes: you get a photorealistic render without setting up a scene. For catalog and advertising images where you control every light and reflection, or for animations, KeyShot is the stronger tool.

Question 2

Can HeyGema open my Rhino or MatrixGold file?

Accepted Answer

Yes. Upload the .3dm file and HeyGema opens it in its 3D viewer, finds the center and side stones, and lets you pick the angle: Front, Side, Top, ¾, Back, a view saved in the file, or any angle you turn to. The 3D file never leaves your browser; only a picture of the view you choose is used for the render.

Question 3

Do I need a powerful computer?

Accepted Answer

No. The render isn't made on your computer: HeyGema runs in the browser on a computer or a phone, with nothing to install.

Question 4

Can I use HeyGema and KeyShot together?

Accepted Answer

Yes. Many jewelers render client proposals with HeyGema and keep a full renderer for catalog shots. For a side-by-side look at KeyShot, V-Ray, Rhino's renderer, Blender and AI tools, see our guide to jewelry rendering software.
