2.Getting Started #

Unity version

Please do not attempt to import this asset into a Unity 2021 project. It will auto-install the Collections v2.5.1 package, which isn’t compatible with this version. You’d have to manually downgrade it again to fix your project.

Under no circumstances must your project contain a script, without namespace, called “Spline” or “Editor”. This wreaks havoc to no fault of this asset.

Importing

At all times you must ensure your project is free of any console errors. Unresolved code errors will prevent this asset’s scripts from compiling. This results in all of its functionality remaining unavailable.

This asset imports as a package so won’t be placed in the “Assets” folder.

These package depencies will be automatically installed:

  • Spline 2.8.3
  • Mathematics 1.3.2
  • Collections 2.5.7
  • Burst 1.8.28

Project Setup

To view the demo scene, a project using the Universal Render Pipeline is required (Default in Unity 6+)

What about the Built-in RP and HDRP? Materials/shaders for the demo scene need to be configured for a specific render pipeline, so inherently excludes others. However, this asset works all the same regardless of any rendering configuration

Scene Setup

This tool use Unity’s native spline system. Familiarity with it is assumed here. Fortunately, it is rather straightforward to work with.

You can find a quick-start guide here:  Quick start

You’ll need to know how to:

  • Create a Spline object
  • Use its editor tool
  • Insert new knots

Component Setup

Time to start creating a spline mesh!

Go to GameObject->Spline->Mesh->Curve/Fill

See the Components section for a general overview of shared settings.
