3D • R3DS Wrap 4D, Metahuman • 2022
MetaHuman excels in creating realistic models, but its potential is truly unlocked when enhanced with photogrammetry. In this guide, I will show my process of transferring textures from a photogrammetry model (from 3D Scan Store) to the MetaHuman using R3DS Wrap 4D.
Photogrammetry
Photogrammetry is the science of extracting three-dimensional information from photographs. Resources like the 3D Scan Store offer free photogrammetry models, which can be combined with the R3DS Wrap tool to transfer these enhanced textures onto your MetaHuman model. The result is a significant upgrade in realism and visual impact.
Step-by-Step Guide to Enhancing MetaHuman Models with Photogrammetry and R3DS Wrap 4D 🛠️
- Generate a MetaHuman Model:
- Use the MetaHuman framework to create and download a realistic human character model.
- Obtain a High-Quality 3D Scan:
- Use photogrammetry to acquire a high-quality 3D scan of a human head from resources like the 3D Scan Store.
Transfer Textures Using R3DS Wrap 4D:
- Import Models: Load both the MetaHuman model and the photogrammetry scan into R3DS Wrap 4D (MetaHuman model in yellow, 3D Scan Store model in pink).
- Wrap MetaHuman Model: Align and wrap the MetaHuman model onto the 3D Scan Store head scan. This step alters the MetaHuman’s shape to match the scan while preserving the UVs.
- Transfer Textures: Transfer texture maps (Normal, Albedo, Roughness, etc.) from the photogrammetry scan to the MetaHuman model. This enhances the model’s surface qualities, such as smoothness, color, and reflectivity.
Fine-Tune Textures in Photoshop:
- Make minor adjustments to the texture maps in Photoshop to ensure they accurately capture your MetaHuman model’s features.
