I have a model of a tomato plant that I am using for a game. I can't get the objects to join properly although I have tried a bunch of different things and different conditions for exporting. There appears to be only 1 object in the Bender outliner, but when I test the model in my game, and in this Open 3D Model Viewer which I have downloaded just now, there are clearly 2.
I am using .3ds for these non-animated models. I opened some of my other models in the same program to confirm that they have the right number of objects, so it is only this one model that has problems. I even have another version with flowers instead of tomatoes, and that one has the exact same problem.
