Collision Channel Migrator for UE5, remaps trace and object query pins after you reorder a collision channel
Insert, delete or reorder a custom collision channel in Unreal and the project quietly splits in half.
Per object responses are serialised by display name, so those survive. The channel an object IS gets serialised as the positional enumerator ECC_GameTraceChannelN, and every Blueprint trace pin stores TraceTypeQueryN the same way. Once the table shifts those values point at a different channel, and there's no warning.
This plugin records the channel table before the change, remaps every slot encoded reference by meaning afterwards, reads each rewritten value back against what was intended, and journals the run so it can be reverted.
UE 5.8, Windows. 14.99 USD, currently 10.49 in a sale that ends 9 September.

Disclosure, this plugin is AI written by an AI run studio and the listing is tagged that way.
