Settings

This page summarizes the most important editor-facing settings.

Planet Data Asset

Setting	Description
Planet Radius	Base radius before elevation.
Noise Height	Normalized height to world displacement scale.
Generation Seed	Stable seed used by terrain material expressions.
Min Recursion Level	Minimum chunk recursion level.
Max Recursion Level	Maximum chunk recursion level.
Planet Material	Visible surface material used by generated terrain chunks.
Generation Material	Computes terrain height and vertex colors.
Biome Mask Material	Chooses biome IDs for the generated biome-cell map.
Biome Layers	Ordered biome entries. Later entries have higher biome-mask priority.
Planet Position Scale	Scale exposed through Planet Position.
Generate Water	Enables water settings and water generation.
Water Material	Near/primary water material.
Far Water Material	Water material used according to the material-change recursion threshold.
Water Simulation Data	Niagara ocean simulation parameter asset.
Recursion Level For Material Change	Water material switch recursion threshold.

Material Output Settings

These controls moved from Planet Data to the material output nodes that use them:

Node	Setting	Description
Planet Biome Mask Output	Biome Cell Resolution	Voronoi cells per cube-face edge and baked map resolution.
Planet Biome Mask Output	Biome Cell Seed	Deterministic biome-cell layout seed.
Planet Elevation Output	Biome Transition	Biome influence falloff width.
Planet Elevation Output	Height Blend Biome Materials	Favors the material of the biome producing the highest elevation.
Planet Elevation Output	Biome Material Height Blend Smoothness	Normalized height range over which lower materials fade.
Planet Elevation Output	Biome Voronoi Warp Strength	Biome lookup warp strength; zero disables it.
Planet Elevation Output	Biome Voronoi Warp Scale	Biome lookup warp frequency.

Planet Spawner

Setting	Description
Use Editor Tick	Enables editor-time generation ticking.
Show Generation Debug	Displays current generation progress and timing.
Planet Data	Planet Data asset used by the placed spawner.
Chunk Quality	Terrain vertex resolution per chunk.
Generate Collisions	Builds collision for terrain chunks.
Generate Foliage	Generates biome foliage.
Generate Ray Tracing Proxy	Generates a ray tracing proxy for hardware ray tracing features. Required for Hardware Lumen; Software Lumen is not supported for generated planet terrain.
Ray Tracing Recursion Level Margin	Number of recursion levels below Max Recursion Level that also build terrain ray tracing proxy data. 0 limits proxy data to the finest chunks; higher values include additional coarser chunk levels.
Collision Disable Distance	Distance for disabling collision.
Async Init Body	Enables async body initialization.
Nanite Landscape	Builds Nanite terrain chunks. Nanite can improve rendering of high-detail surfaces, but chunk build time is slower than normal static mesh chunks.
Generate Second UV Channel	Adds high-precision reconstruction UV channel.
Use Full Precision UVs	Uses 32-bit UV precision when second UV channel is disabled.
Foliage Shadow Cache Mode	Accurate keeps animated WPO shadows correct; Cached reduces invalidation at the cost of rigid shadows.
Foliage Minimum Biome Blend Strength	Ignores negligible biome contributions during foliage spawning.
Global Foliage Density Scale	Global foliage density multiplier.
Enable Niagara Wave Simulation	Runs Niagara ocean simulation.
Max Recursion Water Tessellation	High-detail water tessellation.
Far Water Tessellation	Distant water tessellation.
Generate Custom Depth Water Coverage	Adds custom-depth-only water coverage.
Custom Depth Water Resolution Percent	Custom-depth water tessellation scale.
Custom Depth Water Material	Material used by custom-depth-only water chunks.
Generate Water Skirts	Adds skirts to hide water cracks.
Water Skirt Length Scale	Water skirt length as chunk-size fraction.
Volumetric Cloud Actor	Cloud actor updated by the spawner's cloud utility.
Max Chunk Completions Per Frame	Work throttle for chunk completions.
Max Chunk Generation Starts Per Frame	Work throttle for new chunk builds.
Max Concurrent GPU Generations	Hard limit for terrain/foliage GPU jobs waiting for readback.
Max Concurrent Mesh Builds	CPU mesh build concurrency limit.
Foliage Upload Batch Size	Instance transforms uploaded per chunk per frame.
Max Foliage Instances Per Chunk	Hard foliage cap per chunk.
Max Pooled Chunk Objects	Maximum idle chunk objects kept for reuse.
Max Pooled Foliage ISM Components	Maximum idle CPU foliage components kept for reuse.
Max Pooled GPU Foliage Components	Maximum idle GPU foliage components kept for reuse.
Max Pooled Water Components	Maximum idle water mesh components kept for reuse.
Max Pool Objects Destroyed Per Frame	Maximum pooled objects destroyed per frame while trimming pools.

Foliage Data Asset

Setting	Description
Meshes	Mesh variants with probability weights.
Foliage Density	Spawn density for the entry.
Density Vertex Color Channel	Optional vertex-color channel density mask.
Spawn Distance	Distance at which instances are spawned.
Uniform Scale / Scale	Chooses uniform or per-axis random scaling inside the interval.
Culling Distance	Instance cull distance.
Align To Terrain	Aligns instances to terrain normals.
Min Height / Max Height	Height placement range.
Min Slope / Max Slope	Slope placement range.
Enable Collision	Enables collision for this foliage.
Force CPU ISMC	Forces CPU-backed instancing.
Enable WPO / WPO Disable Distance	Enables material WPO and optionally disables it beyond a hard distance.
Visible In Ray Tracing	Includes the foliage in ray tracing effects.
Pass Terrain Vertex Color To Custom Data	Writes terrain vertex color to per-instance custom data.
LODs	Alternate aligned mesh arrays with activation distance, WPO state, and density scale.
Enable Clustering	Enables deterministic cross-chunk foliage clusters.
Cluster Size Min / Max	Number of members per cluster.
Cluster Radius	Spatial spread of each cluster.
