Get SpatialOS



GDK for Unreal known issues

Known issue = any major user-facing bug or lack of user-facing feature that: 1. diverges from vanilla Unreal design or implementation (e.g. ordering of reliable RPCs), OR 1. diverges from user expectations from a SpatialOS project (e.g. interacting across worker boundaries)

Issue Date added Ticket Workaround?
Order of reliable RPCs is not respected in case of unresolved UObject* parameter. 2018-06-14 UNR-363 Potential user-code workaround to explicitly enforce the order of RPCs.
Dynamic component replication. 2018-07-03 UNR-366 Mimic behavior with static components.
Schema generator fails when the destination file is locked. The workflow is less than ideal as you can’t run it again until you restart the Unreal Editor. 2018-07-16 UNR-350 Ensure destination files/folders are unlocked.
Stably-named replicated actors cannot be referred to by their path 2018-08-10 UNR-473 None

Server travel does not work in multi-worker configurations. 2018-10-24 UNR-678
ReplicateYes policy on GameplayAbilities not supported. 2018-10-24 UNR-675 Don’t use replicated GameplayAbilities. If they need access to replicated data, store it on the AbilityComponent itself.
NetDeltaSerialize or Fast TArray Replication not supported. 2018-10-24 Use default serialization
Non-replicated instanced data on stably-named replicated actors is reset to defaults on world startup. 2018-10-29 UNR-624 Mark the desired properties as replicated, or change them in a blueprint subclass.
Sometimes the player is unable to move when spawning 2018-10-30 UNR-691 Reconnect
