How it works
Once the scene is modelled, lit and styled, the camera, light and composition stay exactly as approved. Only what changes gets rendered again. That is why every variant looks consistent, down to the shadows.
An example
Picture a sofa brand with one model in twelve fabrics. One living-room scene with three cameras gives thirty-six roomset images, plus a detail crop of each fabric, all in the same light. Next season, the rug and cushions change, a new armchair joins the set, and the catalogue gets fresh images without a new build.
What needs new work
A completely new room, a very different angle, or changes to the product's shape. Everything else draws on the scene you already have.
