KUID searching is the primary method used by creators and players to track down specific assets or locate "missing dependencies"—supporting files required for a larger piece of content to function correctly. Understanding KUID Structure A standard KUID string looks like . It is broken down into three key parts: User ID (Creator ID): The first set of numbers (e.g., ) identifies the content creator.

– Sometimes, even with a recursive search, assets may be available for download but were just missed. Select the "Unknown" asset, right-click it, and choose "Download" . If it's available, it will be downloaded and installed.

This requires testing. The wrong substitution will cause "Faulty Dependency" errors or graphical glitches.

Searching for KUIDs is not always straightforward. Here are the most frequent issues and how to solve them.

Communities like the Trainz Discord or specific railroad groups have dedicated channels where members share rare, hard-to-find KUIDs. Step 3: Downloading and Installing the Found Asset

Think of the Trainz KUID Index as a Google for Trainz assets. This website utilizes a powerful bot to crawl through hundreds of Trainz-related websites, including many smaller international fan-sites and independent creator pages. You can simply enter the KUID you're hunting for, and the index will return results showing exactly which website and which specific page contain that missing asset.

A KUID is a unique identification number assigned to every single asset in the Trainz ecosystem—including tracks, trains, scenery, textures, and sessions. No two assets share the same KUID. A standard KUID looks like this: kuid:userid:contentid
