Unreal Engine 5.4 PCG - Ep 7 - Generating bigger worlds

Video tutorial to learn more about the generation modes to generate bigger maps.

In this video we'll see:
* How to scale graphs to cover a big landscape
* What are PCG Partition actors and PCG World actor
* Pitfalls of partitioning
* Hierarchical Generation
* Runtime Generation, with Hi-Gen.

00:00 Intro
01:44 Setup an open world map with some trees
03:10 Inspecting results and understanding the profiler
04:21 Scale the volume to cover the map
05:10 Why a big volume is bad: loading
06:00 Solution to big maps: partitioned components
07:15 Cleaning zombies Partition Actors
07:27 Scaling the volume back to full map
08:04 Combine PCG generation with HLODs
09:12 Pitfalls of Partitioning
13:18 Discovering Hierarchical Generation (Hi-Gen)
15:06 Visualizing which grid size a node was executed on
15:58 Grid size nodes as generation gates
16:35 Still duplicated work, using the second pin of grid size nodes.
17:51 Introducing Runtime generation
19:35 What is a generation source?
20:29 Overriding generation radius
21:16 Hi-Gen with runtime, rocks on smaller grid size.
22:58 Again with grass
24:31 Final result
24:44 Bonus: Seedling on rocks with the mesh sampler
26:39 Filtering points on top of the rocks
28:27 Select points for even more randomness
28:56 Review of the final graph
29:32 Conclusion
