Materials and Surface Presets

PlanetX distinguishes source Section materials, material identities published by Proxy Bake, and generated materials used by Completion and Padding.

#Surface Preset

UPlanetXSurfacePreset is a Primary Data Asset for reusable Completion and planet-surface styling. Assigning it as the Planet Asset's Active Surface Preset lets authoring settings reference that selection.

Use a preset to share materials, terrain or noise character, and visual parameters. It does not replace structural contracts such as Planet ID or Section geometry.

#Proxy materials

Planet Material Override on UPlanetXPlanetProxyComponent replaces the planet-sphere presentation. Section proxy materials must follow the canonical slots and remaps in BakeData. Reordering slots independently can break boundary and padding material provenance.

#Automatic Padding materials

The runtime binder checks generated-visual binding descriptors and Source Material identity before preparing MIDs. A mismatched geometry revision, slot, or texture set can produce an error material or warning.

#Recommendations

• Run Full Validate after changing a Source Material.
• Rebuild stale Generated Material before packaging.
• Preserve material-slot order across bake and visual build.
• Do not use sky materials as ground Proxy Bake sources.
• Limit dynamic materials to parameters that can be captured deterministically.
