Guildford VR - Hero assets (Kings Chamber)

Kings Chamber was a last photogrammetry asset I worked on for the Guildford Castle VR experience. Data collection was delayed due to ongoing cleanup of surrounding vegetation and thanks to that, model was free from majority of wild fern and long grass.

The RAW scan models were supplied by HistoricVR and captured by Jake Nixon (https://www.linkedin.com/in/jake-nixon-b7672b57/). The models underwent a comprehensive workflow, including cleaning, automated controlled retopology, unwrapping and packing using UDIMs, geometry subD and re-projection to polycount above raw triscount, and finally, decimation to a desired level of detail.

The main challenge of the project was recreating a section of the main entrance covered in overgrown ivy. The geometry and texture were reconstructed using a combination of data from the clean side of the entrance and elements from previously cleaned models.

The VR game model might be 10 million triangles and 7x8k UDIMs (unless was decimated and optimized further, but have no knowledge about it at this stage). The original RAW scan had 31 million triangles and 75x8k UDIMs.
