Substance 3D Scanning and Post - processing

A 3D scanning case attempted with a drone, aiming to test some medium - sized assets or those occupying a certain area.
A total of 33 photos with a 4K resolution were taken.
I used Sa to generate the model, employed Pt to add the texture details (normals) of the rocks and handle the roughness, and finally imported it into UE.
Interestingly, parametric replacement of the rock materials can also be carried out by integrating with the asset library.
