Bruno Catani
Systems, reverse engineering, VR — Brazil
I'm a senior software developer and AI engineer. My professional work is Python and C++ backends, LLM agent systems, and large-scale messaging integrations.
Outside that I reverse-engineer Fallout 4 VR. The engine ships without the physical interaction a VR game needs, so I build it: a hand and weapon physics runtime, the reload and ragdoll systems on top of it, and the SDK other plugins consume instead of re-deriving the same engine work.
Documentation
Released Fallout 4 VR mods, Nexus downloads, requirements, controls, and configuration guides.
RPS SDKThe public consumer SDK for the Rock / Paper / Scissors stack. Provider references and examples for ROCK, PAPER, and RPS UI.
RPS FrameworkFO4VR 1.2.72 native addresses, corrected VR layouts, and checked engine calls with explicit physics ownership and epoch rules.
Work
Fallout 4 VR unless noted. Released mods link to Nexus Mods, with documentation and public source alongside them. Check each mod page for current files and known issues.
Runtime stack
VR interaction runtime. Physical hands, weapon collision and grabbing, with 13 independently negotiated developer interfaces.
Coordinates Bethesda’s native weapon animation with ROCK’s controller-driven pose, restoring reload and manual-cycle motion without a second animation pipeline.
Physics-interactive weapon-part reloads. Harvests baked motion tracks from a weapon’s own animation clips, learns engine-driven part motion at runtime, and scrubs parts along their real authored paths.
Active-ragdoll and actor-physics runtime with explicit human-race admission, native movement coordination and pose diagnostics.
Shared world-panel host with stereo depth composition and routed pointer input. Each consumer owns its renderer and ImGui context.
Developer packages
Public consumer SDK for the stack. One module per provider, each with its own headers, reference, and buildable example plugins.
FO4VR 1.2.72 native addresses, corrected VR layouts, and checked engine calls with explicit physics ownership. Two static libraries.
Menus and addons
Personal Access & Loadout Manager: a configurable VR wheel menu for equipment, gestures, RPS settings, and mod-added sections.
Grab walls with either hand, climb, push off, and attempt ledge jumps using ROCK surface interaction.
Tools and graphics
Havok collision and physics-world visualizer for Fallout 4 VR mod developers.
