Recover Missing Assets

This page provides information on how to recover missing assets in Chaos Cosmos.

Overview

When opening an older project that contains missing Cosmos assets, there is a way for these to be recovered. The Recover missing assets option available in Chaos Cosmos works for deleted, moved, shared or otherwise lost assets.

By using the exact name and hash of the asset from the file path, Cosmos downloads the correct version of the asset used previously in the project. This guarantees the missing assets are recovered and rendered the way they were initially.
