If you are diving into the rich and shadowy world of modifying FromSoftware titles (such as Dark Souls , Bloodborne , or Sekiro ), you will quickly encounter the proprietary file formats the studio uses. Modding these beloved games requires powerful tools to extract, edit, and re-pack assets.
One highly specific but essential process in this ecosystem is dealing with the FLVER and SDM formats. While FLVER is the standard 3D mesh format FromSoftware uses for characters, weapons, and environmental assets, SDM generally relates to spatial, bone, or model data mapping.
Re-export your finished configuration strictly as a standard .FBX file. Technical Troubleshooting Reference
Utilize the conversion module to parse your .flver mesh data into the .sdm structural map. This step mathematically calculates the vertex weightings, bone indices, and collision properties required by the target game's engine. Step 4: Finalizing and Re-Packing Bbtools-flver To Sdm-
A FLVER file is the finalized, proprietary 3D model format utilized by FromSoftware's internal game engines. It wraps physical geometric data with complex engine-specific properties so the renderer knows how to display sub-meshes. A standard FLVER file binds several data layers:
The transformed data is inserted into the Sdm- target. This phase requires validation checks to ensure that referential integrity is maintained (e.g., no orphaned records).

Mastering Souls Modding: Converting FLVER Files to SDM and Engine-Friendly Formats using BBTools and Aqua Tools
This is where the (Source Model) conversion process becomes essential. This article acts as a comprehensive guide to understanding, setting up, and executing the conversion of FromSoftware's FLVER models into a usable SMD/Source Model format for custom editing. What is BBTools FLVER?
BBTools, developed by the Joint Genome Institute (JGI), is an integrated suite of bioinformatics tools designed to facilitate the analysis of genomic data. The suite encompasses a wide range of programs, including tools for genome assembly, gene prediction, functional annotation, and comparative genomics. BBTools is designed to be highly customizable, allowing users to tailor the tools to their specific needs. While FLVER is the standard 3D mesh format
SDM files, on the other hand, are generated by the SOAPdenovo2 assembler, a de novo assembly tool that uses a k-mer-based approach to assemble short reads into contigs. SDM files are widely used in genome assembly and analysis, as they provide a compact and efficient representation of assembled contigs.
Now we simulate bbtools-flver to sdm- with a Python script. Below is a universal converter.
