I have been trying to make a costom model to replace the banshee(for pc). I made sure it had less verticies than the original banshee, but when i try to import it with hmt, it says theres too many subobjects.

What are subobjects and how do i make it so its just 1 subobject instead of like 70? HELP!

it is in the material editor.just set the number to 1

I did this, but it still gives me the same error, but this time it says i got 144 subobjects! ?!?!

if u make a model for pc it has to have the SAME number of verticies as the original. get ce if u want to make new models
