# Troubleshooting & FAQ

## Generation fails

* Confirm that the correct provider is selected.
* Verify that your API key is valid and belongs to that provider.
* Check your provider account's access, billing status, usage limits, and model permissions.
* Try another supported model if the selected one is unavailable.
* Check your internet connection and the provider's service status.

## The API key is rejected

Make sure the key is complete, active, and entered under the matching provider. If it may have been exposed, revoke or rotate it with the provider. Never include the key in a support request.

## No model is available or a model request fails

Model access can depend on provider account permissions and current service availability. Check the provider's official documentation and account dashboard.

## I cannot find an imported Sound Wave

Check the import folder configured in SonicForge and look for the asset in the Content Browser. Confirm the destination folder is valid and that the import action completed.

## Imported audio sounds different from the preview

Check the import compression and audio quality settings. Export the original WAV and compare it with the imported Sound Wave to identify whether the difference occurs during import.

## Can I use SonicForge without an API key?

No. You must provide your own API key for the external provider you use. SonicForge does not automatically assign keys or include automatic API key provisioning.

## Are API costs included?

No. Your provider may charge separately for API access and generation. Review the provider's pricing and usage terms.

## Which Unreal Engine versions are supported?

SonicForge is tested and approved for Unreal Engine **5.0–5.8**. See [Unreal Engine Compatibility](/sonicforge/unreal-engine-compatibility.md).

## Where can I get help?

Visit the [Blackridge community on Discord](https://discord.gg/JyFES68sHt). Include your Unreal Engine version, selected provider/model, a description of the issue, and any non-sensitive error text. Do not share API keys or other secrets.
