Summary
It seems that creating a repeatable activate/unload/re-activate flow for a single data layer isn’t working properly.
I’ve created an Activate and an Unload Level Sequence to manage showing/hiding a specific data layer.
The initial display works fine (in both cases where the Data Layer’s Initial Runtime State is either Unloaded or Loaded), as does the Unload, but the subsequent playing/triggering of the same Activate Level Sequence does not work for the second and beyond triggers.
On the second trigger, the assets are visible for a few frames then disappear. Any subsequent combo of unloading and retriggering and they never appear again.
I’ve provided 60 frames of pre-roll time for the activate call, tried adding unload, load and activate within the same sequence, and tried various combos of the Desired and Preroll state in the track’s properties, but the behavior for the 2nd+ activation remains the same.
Is this a supported flow or is there a different way i should be approaching it?
Steps to Reproduce
- Create a new data layer that is configured for Runtime, with an Initial Runtime State of Unloaded
- Assign assets to the the new data layer and verify they are displayed/hidden when changing the visibility of the newly created Data Layer
- Create a Level Sequence (and linked Cinematic Device) to Activate the Data Layer. It should contain 2 tracks, each configured to reference the Data Layer, that Load and Activate the linked data layer (also tried just Activate). It should have sufficient pre-roll frames (default of 60). For the Activate track, set the ‘When Finished’ parameter to Keep State and the pre roll state to Loaded and the Desired State to Activated
- Create a Level Sequence (and linked Cinematic Device) to Unload the Data Layer
- Create two buttons, setup to Play each of the cinematic devices
- Interact with the Activate button and observe the assets are correctly loaded
- Once the sequence playback has completed, Interact with the Unload button and observe the assets are hidden/unloaded
- Interact with the Activate button again and observe the assets are displayed for a few frames, then instantly disappear
- Interact with the Unload and then Activate buttons and notice the assets never appear again
Expected Result
Creators should be able to repeatedly load/activate/unload/re-load data layers.
Observed Result
The second onwards activation does not work. The second activation will display the layer for a few frames, then it disappears. The third, onwards activations, the data layer assets never appear
