Can anyone identify this type of blueprint?

I was looking at some of the road markings in the NS Coal District route and I can't figure out what kind of blueprint this is:

It has gizmos to stretch length and width.

Its called a screen space decal. Its an overlay that can be placed on any scenery object. You could use it to place a sign on a building, cracks in pavement, manhole covers in a road etc. In your case, they are used to place markings on the roadway.

They are easy to make. Its fully described in the TS2014 Developer Docs - Part 1, Section 4.

Awesome. Thanks for the reply Wayne!

Wayne, I was reading the Doc and this part is a bit confusing re: the UV selection (highlighted text):

I'm guessing that you are selecting a portion of the image, but how do you determine these 'coordinates'?

For the simple case, to map the full texture to the decal, the upper left is 0,0 and the lower right is 1,1.

This image shows how it is mapped.

Where did you get a hold of that grid? I wonder if it could be over-laid in the UV image editor...

Make one! Just break it up into equal 8 x 8 squares so that the end result is equal to 256 x 256, 512 x 512, etc.
