PlanetGen changelog

1.9

• Depth-tinted ocean on planets and rings: turquoise shallows fading to deep navy, a shoreline foam line and clear shallows. Stays opaque (Single Layer Water) so it sorts behind volumetric clouds. New Water Depth Colour Range setting, MI_PlanetWater / MI_PlanetWaterRing instances and a flat-colour M_SimplePlanetWater.
• Exclusion volumes (APlanetGenExclusionVolume): flatten level pads on planets and rings and suppress foliage and grass, with Align To Planet.
• Actor spawner (UPlanetGenSpawnerAsset): deterministic, biome-, slope- and height-filtered actor scatter around the player.
• Water traversal on ring worlds: wade and auto-jetpack now work on inner- and outer-surface rings as well as planets.
• Fixed: volumetric clouds were blank on UE 5.4 and 5.5. The 5.6+ cloud reconstruction fix is now applied only on 5.6 and later.

1.8

• Water traversal: the gravity character wades through shallow water (Max Wade Depth) and auto-engages the jetpack over deep water (Water Auto Jetpack Clearance). Multiplayer-safe.
• Water gameplay API: ComputeWaterClearance and GetWaterSurfaceRadiusCm. The gravity queries are now BlueprintPure.
• UE 5.6+ cloud reconstruction fix: High Quality Cloud Reconstruction restores clean volumetric cloud edges.

1.7

• Fast-fly hyperdrive: FastFlyTo(TargetLocation, Duration) with an OnFastFlyStateChanged event.
• Horizon-based chunk culling: loads only terrain visible over the curved horizon.
• Double-precision noise for large planets; Planet Radius up to 1000 km, Tile Size up to 20 km, Resolution up to 513.
• Adaptive water tessellation to a sag tolerance, plus a Live Water Update toggle for the editor.
• Tiered per-chunk LOD (experimental, off by default).

1.6

• Multi-planet LOD: only the nearest planet streams terrain; the rest render as low-poly spheres with an occlusion-based handoff.
• Per-planet atmosphere via UPlanetGenAtmosphereAsset, with one Sky Atmosphere moved to the nearest planet.
• Correct night side: per-sample cloud transmittance and a shader-space day/night terminator.
• Distant-planet halo and cloud shells.
• Editor LOD and atmosphere preview buttons.
• Noise scale check on every noise layer.
• ACLMPlanetSunSky deprecated in favour of ACLMPlanet plus an atmosphere asset.

1.5

• Ring worlds (ACLMRingWorld) with inner or outer surface terrain, windowed streaming and centrifugal gravity.
• Structural shell with collidable end walls, stacked cloud and atmosphere layers, ring atmosphere and post-process fog materials.
• Shape-aware grass and foliage for cylinders.
• Beach Height is now an absolute height in metres.

1.4

• Multiplayer gravity framework: sphere, cylinder and box gravity volumes with priority, plus a gravity subsystem.
• Prediction-correct movement with UPlanetGenGravityMovementComponent.
• Per-source gravity strength and zero-gravity regions.
• Gravity character (APlanetGenGravityCharacter, BP_GravityCharacter, BP_GravityJetpackCharacter) with orbit camera, jetpack and zero-g flight.
• The single-player ACLMPlanetCharacter / UCLMPlanetaryMovementComponent are deprecated.

1.3

• Spatial climate biomes: Tundra, Boreal, Desert and Tropical.
• Polar ice caps and a desert sand layer (UV1.y).
• Climate filter on foliage and grass assets.
• Planet slope mask and seamless cross-chunk normals.
• Beach flattening and sample desert flora.

1.2

• Player-following grass decoupled from chunk loading, with a per-frame upload budget.
• Per-instance collision range on grass assets; clustering, jitter and shadow control.
• Enable Foliage / Enable Grass toggles and a Preview Size (Water Only) button.
• Target Sun Sky Actor and Sun Shadow Distance.
• Single Layer Water material (M_PlanetWater).
• Max Chunks Per Face memory guardrail and faster noise.
• Uniquely prefixed types, so PlanetGen installs alongside other CodeLikeMe plugins.

1.1

• ACLMPlanetSunSky now sets the Sky Atmosphere’s transform mode automatically when you click Preview Planet.
• New BP_CLMPlanetSunSky Blueprint and PlanetMap_Atmos demo level.

1.0

• Initial release: cube-face spherical terrain, 3D noise sampling, async mesh generation, biome blending, beach layer, foliage and grass scatter, procedural water sphere, radial gravity, IPlanetInterface, and seeded generation with Randomize.
