Using union-parts in a morph?

Hi,

I've recently been trying to make a simple morph with union parts being included in it. The problem I have however is that when your character changes into the morph it does not include the parts and they just rather don't show up at all. Is there any solution to this? I have not included any code besides one that changes it's speed, but that's not the problem. I found my way here at Scripting Helpers as I was looking in the ROBLOX forums and a person stating that you should look here. Not sure if I need welding or anything like that, it's just the fact that the union parts don't show up yet other "normal" parts do.
