I have a 3DS Max model of an inhaler which is made up of two parts, the actuator and the cap. When I export the file as a .obj file the cap and the actuator are classed as 1 part.

How do I export this as a .obj file that recognises the actuator and the cap as being separate objects?

  • Questions about 3D are really only limited to composition as it pertains to design. Technical questions are off-topic.

  • I do not think there is much you can do about how the exporter and any subsequent importer works. Write your own exporter.

I found a solution by converting the source file on this site: https://clara.io/ Object did not separate geometry, but you can give a name to different "OBJ Groups". I advice to you export in FBX format if you want to get different meshes insted just one.

And me I'd want to have you look carefully at your UV islanding, and seeing where you have vertices merged to be sure that your separate parts really are separate... if they are, .obj should support that - but the recent answer suggesting .fbx is not incorrect - there are many instances in which you get a lot more data passthrough with .fbx.
