Mem for Deadlock

Overview

A personal Deadlock mod that replaces the hero Rem with Mem from Honkai: Star Rail, so you play as Mem in the game. She holds a book where Rem's candle was and a quill where the hugged pillow was.

The problem

I built it for fun.

What I did

• Wrote the fitting pipeline in Python and Blender: it strips the model-viewer-only bones and physics from Mem, then scales and poses her onto Rem's 195-bone skeleton, remaps the weights, adds the book and quill, and exports the result in the game's model format.
• Made Mem's expressions work in the game. Rem never animates face morphs, so I swapped body groups instead, with an eyes-closed Mem for sleeping and a smiling Mem for the hero portrait.
• Replaced the thrown pillow with a book projectile, recoloured the particles pink, and turned Rem's helpers into Trailblazer's Chimera.
• Made the interface art: Mem portraits and expressions, a quill gun icon, white ability icons and a pink splash background.
• Wrote a one-shot build script that compiles, stages, packs and zips each version, and a small tool that re-enables mods after Steam resets the game's settings.

Stack

Python and Blender (with Blender Source Tools) for the fitting scripts, Source 2 Viewer and the CS2 Workshop Tools compiler for decompiling and compiling, and PowerShell for the build and install scripts.

Outcome / impact

Three releases, v1.0 to v1.2, working in game. It is for personal use only and is not distributed: Mem, the book and the quill come from miHoYo's official model release, whose rules allow modifying it but forbid redistribution, so the repository holds only scripts and project files.
