Photogrammetric Rocks - Cluster Workflow

This is what I did to create the clusters and their LODs. The LOD making part is not good because it create a specific mapping & texture for each LOD. I went with a better workflow when I did the optimized version asset for Unity & UE4. Basically I UVmapped the first LOD then I used Balancer to decimate properly (better result than Meshlab at that time) the mesh while preserving the UVmapping as mush as possible.
