It's not fully functional yet, and the input pins need to be reordered, but my first custom C++ #UnrealPCG node can be compiled, added to a graph in the test project, and doesn't cause a coredump of the #UE5 engine.

I've created many custom nodes in Blueprint, but this is my first in C++.
The image is a screenshot of a single node from the Unreal Engine 5 Procedural Content Generation (PCG) system. This custom node is titled "Get Asset Data set". Data connections to this rectangular node are represented as labeled "pins", each of which has a small icon and a text label. Input pins (on the left side) are labeled "Execution Dependency", "Overrides", "Data Assets from Input", and "Data Asset". The sole output pin (on the right side) is labeled "Out". A small up-arrow icon at the bottom indicates the node can be partially collapsed to hide advanced input and output pins.

[WIP] Progress on procedural level tools. I generate the walls from splines with Geometry Script but bake to instanced static meshes for runtime. Created this wall-finding custom node so downstream PCG can accept the generated ISMs as well as hand-placed architecture. #UnrealEngine #UnrealPCG
Unreal Engine editor viewport shows an oblique view from slightly above a prototype level with multiple rooms and moderately complex layout. There are white cubes and very thin red and green lines indicating where raycast traces have sought and detected the wall geometry. The traces originate in a grid on 2 meter intervals, so the white cubes along the walls are also spaced 2 meters apart.

First successful test of procedural holes in my prototype level for a side-project game. The landscape is runtime generated, including holes for tunnels and mine elevators. #ShaderWorld plugin for #UE5, with lots of #UnrealPCG to connect hand-modeled rooms with procedural map layout and tunnels.
A third-person character stands just outside a blockhouse-like tunnel entrance with a stairwell descending below the grassy terrain. The tunnel is dimly lit from within, while the landscape and exterior are in daylight. The tunnel entry structure is a blocky prototype covered by a grey checkered test pattern. The third-person character is the standard Unreal Engine mannequin, humanoid proportions but with non-realistic silver-grey skin and no facial features.
