This model is called San Pedro or Echinopsis Pachanoi cactus. I made this with 3D scanning or photogrammetry technique. This model has 5 different vols, which vol1 is high poly and vol5 is low poly. You can see the verts value of each model in the pictures and at the bottom of this description. Also, all 5 models have the same UV, and the textures are set for all of them.
