What’s new

Unreal Engine

Surface partitioning

Added integration for the Surface Partitioning feature to our Unreal Engine plugin. This feature allows you to skip creating a big texture that covers your entire screen, and instead render only the visible parts of your UI in small, separate textures, thus reducing your memory footprint. The feature works with both UMG and HUD setups, and enabling it is as easy as clicking a checkbox in the Unreal Engine editor, then marking the parts of your UI to be drawn in the HTML. For more information, check out the new Surface Partitioning sample map or the Unreal Documentation.

Using the surface partitioning feature, you can create textures only for the circled parts of the UI

Unreal Build Settings Version V2

Switched to Unreal BuildSettingsVersion.V2 and Include-What-You-Use(IWYU)

The Prysm plugin now utilizes the BuildSettingsVersion.V2 (more on the UBT Build Properties here) and the Include-What-You-Use(IWYU) (controlled by the IncludeOrderVersion property) build settings, both of which should result in faster build times.

Additional build properties that were explicitly set in accordance with the latest UE version are:

  • Changing the PCHUsage to PCHUsageMode.UseExplicitOrSharedPCHs
  • Setting the ShadowVariableWarningLevel to Error level
  • Disabling the bLegacyPublicIncludePaths property

All relevant .Build.cs and .Target.cs files have been updated.
