Parts of Model not appearing

[Muzzles56]

This is my first time modeling, thanks to Darth Maul for teaching me, and Ive made a very basic model

However, when I export it into Blockland, packaged correctly, this is what appears in-game

When I export the model, I export it to Torque DTSPlus and set all LOD numbers to 0. I have also welded everything together. Where am I going wrong?
I have tried to remake this add-on many times, and each time, different parts disappear. Is it a problem with the script or the model?

I do not know if milkshape has Detail32, but make sure the all of the objects are parented to it.
