The platform for architects. Starting with renders.

Change one layer. Keep the rest.

Relight an approved render. Your design stays as drawn; every change is measured, and a named person signs it off.

Questions

No. It is an AI-assisted or physically rendered image of a design, and every result says so.

No. Camera, geometry, openings and materials stay as drawn. Only light, sky, exposure and atmosphere may change, and each change is compared with the original. When Plyvel renders a model itself, it uses preset lights, frames the camera automatically and shows missing materials in grey; the model is not changed.

Into the data folder on your own computer, and nowhere else. Nothing leaves this computer and nothing is shared.

Which files were bound together, by hash; what each check measured and against which threshold; who reviewed each group and what they wrote; and that the archive has not changed since it was signed. It is evidence, not a certificate.
