Oh, so that would be some sort of... It could be down to a material, or it could be that it's a mesh that's set to transparent, and then therefore you can't shoot through it. We try not to use invisible collision. And I think on some grating... So on this, for example, if the AI is below you, they can't shoot you and you can't shoot it, because the holes are too small. But on, say, a chain-link fence, that's when you might be able to have things pass through, because that's more likely to have bullets passing through it. So it's kind of finding the line of: do we want the people to fight each other through this, or is it just too much of a bad gameplay experience, so therefore we make it so that you cannot?
