In this tutorial i will give you a complete walk-through of creating a real-time ready asset using photogrammetry. I will cover everything from capture best practices and image processing to solving your data in Agisoft Photoscan to retopologizing and cleaning up and creating your PBR texture set in Substance Painter then finally setting up everything in Unreal Engine 4.
