Export from Blender to 3ds

So I’m playing a game which allows you to import custom assets (IE buildings, spaceships etc) however they only accept STL and 3ds formats.

I can import STL file but it has no textures, so I need it to be 3ds format. However Blender 2.82 doesn’t seem to offer the option to export to 3ds and I can’t seem to find any tool that will do it for me. I have a tool that converts the mesh to 3ds, but it doesn’t have the materials (mtl) etc then?
