Spent the last few days digging into the asset structure for custom agent models in Valorant. Anyone trying to inject or preview modified PAKs is hitting the same wall with CUE4Parse when the IoStore headers don't align with the local global data.
The Error Breakdown
If you are seeing this output, your environment is missing the necessary global IoStore data to serialize the container:
Technical Reality
Valorant uses a heavily customized IoStore implementation. Simply dropping your cooked .pak files into the directory won't bypass the integrity check or the need for the correct global metadata. FModel requires the full directory structure to resolve the virtual paths correctly—it isn't just about the .uasset files.
While others are trying to shove raw files into the folder and hoping for a miracle, the reality is that you need to align your custom containers with the game's current manifest architecture. Has anyone successfully managed to override the local model assets without triggering the integrity mismatch on boot?
Anyone else working on custom PAK injection for Valorant?

- Ensure your AES keys are strictly for the current game version; if the global container header is version-mismatched, it won't deserialize.
- Check if your custom PAKs were cooked with the specific engine build used by the current Valorant client. Mismatch here is the most common cause of serialisation failure.
- Verify that your path mapping in FModel matches the internal virtual path structure of the game's manifest.
If you are trying to preview these inside FModel, you need to point the provider to a fully populated game directory. FModel needs the global store to link the dependencies defined in your custom skeleton mesh. Trying to load the PAK in isolation without the base game's global IoStore data will almost always result in a null pointer or serialisation exception.
