Collision Channels

Note: As of version 1.3.2+, the system automatically creates the required channels. If you're using UBS for the first time, you can skip this step. If you're upgrading from an earlier version, you must delete any old channels manually.

  • If you see multiple channels like BuildableProxy, BuildableSocketTrace, BuildableSocket, or Buildable, simply delete all of them and restart the editor. The system will automatically recreate the correct channels on startup.

Note: If you're upgrading from a previous version of UBS to 1.3.2+, make sure to review any custom Buildable Definitions you've created.

  • Any Buildable Definition that uses proxy behavior, dependencies, or other logic relying on an object or trace channel must be checked to ensure it's using the correct channel.

  • In any placement condition, if the channel is set to:

    • GameTraceChannel

    • BuildableSocket

    • ConstructibleProxy

    • BuildableSocketTrace ...must be updated to Buildable.

There's a few custom trace and collision channels that needs to be setup correctly.

You will need to go into the Collisions Section of the Project Settings to set these up.
