@Topo-0 Hey, hello! Yes, there is a very long document about this on the GitHub page of the BMS exporter. Here is the link:
https://github.com/BenchmarkSims/bms-blender-plugin/blob/main/docs/Manual/MANUAL.md
And there is also a three-part document about building an aircraft from scratch and transferring it to BMS, but I’m not sure how useful it will be in 3ds Max. However, it will definitely help a lot with making models for BMS !
