Before diving into this, I'd need to have some tests run against TDM to see what it does to a model with known vertex and poly count (ASE and LWO). I've read the code, but before changing the behaviour I need to be sure what the engine is doing. This way I can also create the corresponding unit tests. |

I've attached building_sewer_35.ase and building_interior_25.lwo. They are both complex models, and this version was exported before 5115 and 5116 were resolved, so they should both contain thousands of excess verts that TDM or DR would attempt to remove. building_sewer_35.ase 86376 verts according to DR 86376 verts according to Blender 20192 verts if turned into an .lwo by DR building_interior_25.lwo 28044 verts according to DR 43236 verts according to Blender |

A complicated model is fine for characterising the behaviour, but I would recommend creating small models for the unit tests to avoid inflating the Git repository size with a 21 megabyte ASE file. You might only need a simple cube to test vertex merging. |

Yes, that thought occurred to me - fortunately there are already 2 simple .ase and .lwo models that I attached to a related ticket, 0005115, that could be used for the unit test once this has been solved. |
