    So I've been trying to make a render scene in 3ds Max 2017, and I've run into some issues. I made the scene by taking the render scene that comes with BR15 and cloning that car to get a 4 car scene. My issue is that some of the cars are rendering without the hood flaps. I've researched the issue and have seen people say it's the underhood geometry, but I've played with moving and removing that to no avail.

    It maybe an issue of the under side of the hood clashing with the top causing it to render badly or other objects conflicting. A trick to check that is to turn all unnecessary parts off or break the model down and delete polygons.

    Like I said, I've tried that and it didn't help in this case.

    It is a bleeding issue caused when objects are to close together. could be the hood underside etc. nr2003 is fine with it, but Max is a different animal.

    What render engine are you using?

    If you select move the geometry, make sure ignore backfacing is ON.

    Mental Ray, I don't think it's the render engine itself though because in the preview you can see the flaps are gone too. I also just tried the ignore backfacing setting that you suggested and it didn't help. The cars are fine until I assign the new materials to them, that's when they break, but I can't seem to find anything that's to my knowledge wrong with the materials.

    Throwing up an image of what I meant by it being botched in the preview. Firstly when I drag the new material onto the car it applies to everything as you can see, although I've figured out a way around that, but if you look closely you can see the flaps are gone. I'm at a loss.
