CameraVolumes plugin was updated for UE 4.26.2, 4.27.2 and 5.0.
The UE5 version should be available on the Marketplace for free for those people who already bought it for UE4.
Update 19/04/2022:
Plugin:
Added UE5 version.
Updated 4.26 and 4.27 versions to latest changes.
SetCheckCameraVolumes function was deprecated. Use SetProcessCameraVolumes instead.
SetUpdateCamera function has changed its arguments, so you should update its usages.
SetPerformBlockingCalculations function has changed its arguments, so you should update its usages.
Added bDisableCameraLocationLag and bDisableCameraRotationLag flags to camera volume actor to
have an ability to disable those features in particular volume without additional scripting. Please notice
that camera movement without these lags looks more “attached” in some cases.
Added bDoCollisionTest flag to camera volume actor to have an ability to disable this feature in
particular volume without additional scripting.
Added new packaged example projects for Windows and Android platforms - Packaged - Google Drive
Due to obsolescence, plugin support for UE4 versions older than 4.26 was removed.
But plugin code is very portable and can be compiled even under UE4.21, if you really need it.
