The bbtools-flver tool is a specific program within the BBTools suite, designed to convert FLV files to SDM files. FLV files are generated by the FLASH (Fast Length Adjustment of SHort reads) assembler, a popular tool for assembling short reads into contigs. However, FLASH-assembled contigs may require further processing and analysis, which can be facilitated by converting them to SDM files.
Raw 3D point data, normal maps, tangents, and UV coordinates.
| Problem | Likely Cause | Solution | |---------|--------------|----------| | bbtools-flver: command not found | Wrong tool name or missing binary | Use the FLVER Editor + Python pipeline above | | SDM output has no bone weights | SMD export didn’t include skeleton | In Noesis, tick “Export skin weights” | | Normals are wrong in engine | FLVER uses tangent space normals, not model space | Recalculate normals or convert via custom script | | FLVER version unsupported (e.g., FLVER4) | Outdated tools | Use WitchyBND for Elden Ring FLVERs | | SDM file too large | Unoptimized vertex count | Run FLVER through a decimation tool (Blender with CATS plugin) |
This article provides a comprehensive workflow to convert FLVER to SDM, covering necessary tools, step-by-step instructions, common pitfalls, and post-conversion optimization.
This is the simplest, most satisfying step. Using your mouse, click and drag the .flver file (e.g., WP_A_0300.flver ) and drop it directly onto the BloodBorne_model_v3.exe icon. A command prompt window will flash open for a moment as the tool processes the file.
While finding the tools and troubleshooting the initial errors can be challenging, the reward of seeing your own custom creation come to life within the intricate worlds of Elden Ring , Dark Souls , or Bloodborne is an immensely satisfying achievement. Remember to consult the extensive wiki resources, like the Souls Modding Wiki, and to share your own knowledge with fellow modders as you advance on your journey. Now, go forth and create. The workshop is open.
