The Hidden Cost of Commissioning 3D Product Models Twice

When we audited our 3D spend, the headline number was roughly what we expected. The breakdown was not. We had paid to model a meaningful number of products more than once, in some cases three times, and nobody had done anything wrong.

How it happens

It happens because three different teams buy three different things at three different times:

• Marketing commissions a hero render for a campaign
• The web team commissions a configurator model six months later
• Someone commissions an AR asset when AR arrives

Each brief is reasonable in isolation. Each supplier delivers exactly what was asked for. And each asset is optimised for its own use in a way that makes it useless for the others: the hero model is millions of polygons with no UVs worth speaking of, the configurator model is clean but has baked-in materials, the AR model is aggressively decimated.

The master model approach

What we moved to, eventually, was a single master asset per product with a defined derivation path: one high-detail source, from which the render asset, the configurator asset and the AR asset are all generated to spec.

That requires deciding the spec before the first commission, which is the part organisations find hard, because at the point marketing wants a hero image nobody is thinking about AR.

What it saved

Roughly forty percent of our per-product cost, and more importantly it fixed a consistency problem we had stopped noticing: the sofa in the campaign image and the sofa in the configurator were visibly different shades of the same fabric, because they had been authored separately.

The organisational fix

One owner for 3D assets, sitting outside any of the three teams. Not a technology decision, a governance one. When we briefed AR 3D Modeling on the catalogue rebuild, the first thing they asked for was the derivation spec — which told me they had seen this failure before.

If you are starting now

Write down what the model will need to do in three years. You will be wrong about the specifics and right about the pattern, and that is enough to avoid paying twice.
