https://doc.cdryx.net/CdryxAIOUPlugin/cworldumodule/cabstractworldmaker/index.html Overview UCAbstractWorldmaker is the abstract base class for terrain generation. It manages the tile grid, LOD computation, async build pipeline, noise blending and mesh lifecycle. Concrete implementations (UCWorldmaker_ProceduralMesh, UCWorldmaker_DynamicMesh) provide the actual mesh creation. Pure Virtual Functions Name Description isFirstStart Returns true if no mesh has been created yet cleanPmc Destroys the mesh component at a given UV index calculatePoint Computes tile mesh data (LOD, vertex count, transform) for a world/relative UV pair createPMC_sync Creates mesh components on the game thread from pre-calculated data debug Toggles debug material on/off for all mesh components // These must be implemented by subclasses: virtual bool isFirstStart() = 0; virtual void cleanPmc(FCUVIndex index, bool clearContent, bool remove = true) = 0; virtual void calculatePoint(const FCUVIndex& world, const FCUVIndex& rel) = 0; virtual void createPMC_sync(const TArray<TPair<FCUVIndex, FCUVIndex>>& pairUVArray, bool poolStart, int poolSize) = 0; virtual void debug(bool onOff, UMaterialInterface* debugMaterial) = 0;Build Pipeline Name Description buildASync Entry point called by the spawner.
