WP: Water surfaces are missing from the Minimap textures.

The problem is caused by FWaterViewExtension::ShouldHaveWaterZoneViewData that prevents the water data from being updated in SceneCaptures. (re: FWaterViewExtension::SetupView)

Removing the call to ShouldHaveWaterZoneViewData  at line 533 (FWaterViewExtension::SetupView) does allow for the data to be updated but the data might not be ready for some of the tiles. 

I was able to get the data properly generated by adding calls to FWorldPartitionHelpers::FakeEngineTick in the warmup loop in FWorldPartitionMiniMapHelper::CaptureBoundsMiniMapToTexture

I shelved my debugging code in CL49651291

• Create a WP level and add water bodies.
• Build the minimap
• The water surfaces are not captured.
