This page provides information 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.
This option is supported in Chaos Cosmos 2024.09.12-475175 and later.
Steps in Autodesk 3ds Max and Maya
Open the scene in the 3D host application.
In 3ds Max, a pop-up message appears notifying that there are missing Cosmos Assets and their expected file paths. Copy the file paths.
In Maya, you can find the list of missing assets' paths in Windows > General Editors > File Path Editor.
You can use a screen-grabbing tool that recognizes text to take a screenshot and copy the paths.
