I've been making AVIs using motion studies. Gradually, the assembly that I'm using has been getting larger. I added a couple of sub assemblies recently that are for some reason showing up grey as opposed to the colors I assigned and when I open up a motion study they appear very distorted. I've resolved all of the parts and assemblies and I made sure large assembly mode was not on. I've attached two AVIs; the first shows a brief animation of the piece of equipment I've added to the large assembly in the second AVI. You'll notice in the second that the model appears grey and distorted (semi transparent). Any suggestions on how I can make it appear as it does in the first AVI?
