I have been trying to use PDG in Unreal Engine using Houdini Engine and so far the results and the workflow are good apart from the inconsistent UnrealMaps I get after I hit Bake on the PDG user interface for the Landscape results.
Some Landscape tiles are being saved as "Untitled" and do not open nor do they properly load the Map Chunks.
Using Houdini Core 19.0.455 + Unreal Engine 4.27
Is this a known bug?

After some debugging, turns out i had a `@mask` layer that was disrupting the world comp.
