Hey, congrats on re-finding the helicopter! Could be useful in an image. When you download one of my VOB objects, the materials should all be present already...they may not be "the" materials you want, but it should look like the rendered preview image. If you open the Material Browser, you'll be able to see all the materials being used without needing to poke through the model parts. Of course, if you downloaded a DXF model, that won't have materials. And you're welcome, re the parts-naiming. I learned early on that particularly when working with primitives, if you set up something and don't name it, you won't have any idea later which "sphere" or "cube" is which. Using relative names saves a lot of work, and it's also helpful later on, like if you just want to change the color of that trim-piece...now where is it? Ah, there it is, the piece marked "trim." :)
