I input ‘r.HZBOcclusion 1’ in FirstPersonExampleMap(UE5 EA) , it does not work corrently.
But HZBO can work in UE4 4.27.2.
So how to fix it in UE5?
By default in UE5 its switched off and you have to edit the line in
C:\Users\Owner\source\repos\UE50\Engine\Config\BaseDeviceProfiles.ini
about line 282
; HZB will be slower with tiled, and not needed
; HZB will be slower with tiled, and not needed
+CVars=r.HZBOcclusion=0
This will need to be
CVars=r.HZBOcclusion=1
The values on the command line are overridden by those in the control file
From the Ue5 source code
TEXT("r.HZBOcclusion"),
| TEXT(Defines which occlusion system is used.\n) | |
|---|---|
| TEXT( 0: Hardware occlusion queries\n) | |
| TEXT( 1: Use HZB occlusion system (default, less GPU and CPU cost, more conservative results)) | |
| TEXT( 2: Force HZB occlusion system (overrides rendering platform preferences)), |
