WHAT IS A KUID?

A KUID is a serial number that is allocated to all content created for Trainz and can be thought of much like a bar code. A KUID takes the form of two numbers each separated by a colon; for example, 98765:43210 would be a KUID. As you can see, there are two numbers, one to the left and the other to the right of the colon.

USER ID
The number to the left of the colon in a KUID is the USER ID of the content creator. This is the same number you will have entered into Trainz when you told it your USER ID and the same number that you got from the Planet Auran 'YOUR USER ID' selection. In fact, every member of the Trainz community who is a member of Planet Auran gets a USER ID. Now, you may be wondering why you need a USER ID if you don . t intend to create any content for Trainz (like a new locomotive for example). Well, if you intend to make a layout at some point in time and you'd like to share that layout with your friends or other community members, then you are in fact a content creator.

CONTENT ID
The number to the right of the colon in a KUID is the CONTENT ID. This is a number that the content creator assigns to each of their creations to uniquely identify them. The only circumstances where you would not assign a KUID to one of your creations in the case of a saved layout, or when exporting from Trainz Paint Shed. In these circumstances, number allocation will be done for you automatically with a number starting at 100,000 and going up from there. Numbers below 100,000 therefore are designed to be used by those members of the community who make other items of content (not made by Surveyor or Trainz Paint Shed). In that case they can specify the number they use and there are guidelines governing the use and allocation of these numbers later in this document.

Side note:  In case you're wondering, two individual content creators can use the same CONTENT ID for their creations and Trainz will still be able to uniquely identify them since each CONTENT ID is preceded (To the left of the colon) by a USER ID. In other words 1:1 is seen a differently from 2:1 by Trainz.

CONTENT ID RANGE GUIDELINES

Sidenote: Always use a new Content ID for each new item of content. For each new version of content make sure you use a new Content ID and make use of the obsoletes field of the config.TXT file.

KUID Syntax: kuid <KUID:xxxxx:yyyyyy>
The xxxxx is your USER ID.
