Could you build this?
No MuJoCo is a research-grade physics engine built by DeepMind; its contact solvers, deformable-body models, and collision handling require specialized numerical simulation and robotics expertise.
What it would actually take: A comparable engine needs C/C++ with a high-performance constraint solver, collision detection (convex and mesh), numerical integrators, and a GPU or MJX-style pipeline for a studio tool. This requires graduate-level physics and numerical methods and a team to validate accuracy against real-world behavior.
