3D Artist Marco Moschetta has created this realistic Cannon Mortar. In this article, Moschetta talks about the software he used, such as Maya, ZBrush, Substance Painter, Marmoset Toolbag, and Unreal Engine 5. Throughout the tutorial, he explains each step of his creation process, from blockout to low/highpoly modelling to UVs, bakes, texturing and rendering.
