If your manufacturer has a CAD file, import it into Blender directly. If not, search Sketchfab or Fab for a similar existing model ($10-$50) instead of modeling from scratch. For simple geometric products (bottles, boxes, packaging), the Blender Guru donut tutorial teaches you enough modeling to build one yourself in an afternoon.

The Principled BSDF shader handles almost every real-world material — glass, brushed metal, matte plastic, fabric — by adjusting a handful of sliders (roughness, metallic, transmission). This is the single highest-leverage skill for product renders: good materials on a mediocre model beat perfect geometry with flat plastic-looking materials every time.

Download a studio or softbox HDRI from Poly Haven and drop it into Blender's World settings. This one step replaces hours of manually placing area lights and gives you the even, professional-looking reflections that make a render look like it was shot in a real studio.

Use Blender's Eevee renderer while you're setting up the shot — it's near-instant, so you can iterate on camera angle and lighting fast. Switch to Cycles for your final export; it ray-traces properly and is what gives professional renders their believable reflections and shadows, at the cost of minutes instead of seconds per frame.

Amazon's main image spec wants pure white background, square crop, product filling 85%+ of the frame. Bring your render into Canva or Photopea to hit those exact specs, plus create the lifestyle/context versions for your website and social that a plain white-background render can't do alone.
