This 3D knife model was made using Blender and Substance Painter. I first made the high-poly model of the knife using a variety of hard surface modeling techniques, including beveling, subsurf modeling, non-destructive modifier, etc., in Blender. Then, I baked the normal maps onto a low-poly model that is game-ready and did UV unwrapping on the low-poly model. Finally, I imported the model into Substance Painter to apply textures onto it.
