Will the current Trainz FBX exporter for Blender support the newer versions of Blender like 3.0? And what is the current version of the exporter if not for 3.0? Where can it be found?
If you only want to export for TANE/TRS19, no special exporter is needed you can just use the built-in FBX exporter. If you want support for earlier games, you'll need a .IM exporter. If you're using Blender 2.8 and above, you can use this exporter: https://github.com/rileyzzz/BlenderIMExporter
