When you say combined into one single mesh, do you mean I literally have to have the entire object be contiguous and unbroken, or could I just parent the objects to a single object? Right now parenting the pieces to the skeletal bones is the only way I know to rig it. I will have to look into more traditional methods.
Thanks for the compliment on the mech, but I’d actually like to add a disclaimer. This mech was the quickest, most lousy mech I could make in order to experiment with rigging and exporting, and is largely based on a tutorial. So…I’m just saying, not representative of final product.
