Learn how to set up a Rails tool which generates a rail system by drawing a curve. This overhead infrastructure is used to move trains around the Project Titan level.

Project Titan is an in-house tech demo designed to production test Houdini's procedural workflows while creating a 3D environment that leverages the latest technologies in Unreal. Click Here to learn more.

PROJECT FILES
Overview
A quick overview of all the different parts of the rails tool lesson. Take a look at where you are headed with this lesson.
1 | Copy Models On The Curve
Learn how to fit models of different sizes on a curve. The series will focus on placing instances of models on the curve. This is done by having large, medium and small pieces, each of which has a logic behind it that places it in the correct position.
2 | Create Digital Asset
Learn how to make a digital asset out of the node network. This will create a single node that can be used in Houdini to generate multiple rails from curves. You will also make a custom parameter to give the level artist control over the final look.
3 | Open In Unreal Engine
Learn how to open and use the tool in Unreal Engine. Learn how to drag and drop the tool then assign a curve to start working with the tool. Learn how to set up instances in Houdini so Unreal knows what models to use to suit the context.

    Hello,
    I am having a strange issue following exactly the same passages:
    when I use the @restlenght attribute and call for the large/medium/small portion I only have the blue value spread on the entire curve, and I know for a fact that the curve is as big as the one in the tutorial, same goes if I use the blast node, I'm only able to blast the small group, the other two are not catching anything.

    I've got the same values and the same shape of the curve either, stretching from the grid 0 point to roughly 25 units.

    Is there anything like measurement or unit value that I have to check?

    Thanks in advance
