Houdini Heightfield Pipeline: NASA Lunar Terrain → Unity 6 URP

I need an experienced Houdini artist to build a heightfield terrain pipeline
that processes real NASA lunar elevation data (LOLA DEMs) into Unity 6 URP-ready
assets. This is for scientifically accurate visualization of a specific lunar
crater region - NOT procedural generation.

The primary challenge: preserving steep crater slopes (30-45°) that standard
Unity terrain tools cannot handle accurately. Your Houdini workflow must maintain
scientific fidelity of the NASA source data while optimizing for real-time
rendering on integrated GPUs.

Key deliverables:
- Documented Houdini .hip file processing NASA heightmaps → Unity assets
- Terrain tiles with 3+ LOD levels maintaining slope accuracy
- PBR texture sets: Albedo (from LROC imagery), Normals, Roughness, Slope maps
- Elevation precision validation (Unity measurements must match NASA data ±1%)
- Complete pipeline documentation for processing additional regions

Timeline: 3-4 weeks, 3 milestones
Budget: $250-750 USD

REQUIRED IN BID: Answer three screening questions (see attached REQUIREMENTS.md)
- Elevation data format experience
- Steep slope preservation approach
- Portfolio example of real-world data terrain work
