MO RT 120 F1 – French 120mm Mortar

This project is a complete game-ready reproduction of the French MO RT-120 F1 120mm mortar, including the APX 558M optic, several ammunition types, propellant charges, crates, and support assets.

I started this piece as a personal challenge: recreating a full French mortar system with the level of accuracy and care you would expect in a AAA military shooter.

The goal was to push both modeling discipline and texture quality while respecting real-world references and manufacturing details. I especially wanted a clean workflow, optimized topology, and realistic wear grounded in real usage.

The entire asset pack is fully modeled, UVed, textured, and rendered by me.
Everything is game-ready, cleanly optimized, and using a consistent PBR workflow.

WORKFLOW SUMMARY:
