If and when the asset is updated to the latest trainz-build version, such warnings message will become error-flagged and must be fixed. This helps avoid the scenario where large numbers of assets are required to be updated immediately after a new build of Trainz is released.

When adding a new error check, we often treat the resulting error message as a warning for older assets. N3V Games regularly enhances the validation process based on problems found in real Assets. "Warnings" indicate potential problems these often won't prevent the asset from working but may cause it to behave in an undesirable fashion. "Errors" indicate problems which will prevent the asset from being used in the game. If problems are found during validation, the asset is flagged as having errors and/or warnings.

This process is known as "validation" and consists of the following steps:

Each Asset that is installed into Trainz is automatically checked for a variety of problems.
