I think Leopardi's point was, that the chains
can look good even if they don't move around with the vehicle and are done by textures.
IF we end up doing the chains, it'll be modelling the chains in high detail and then baking down the color, spec, normals and alpha. Seeing that it's quite a hassle and the model doesn't require an alpha layer otherwise, it's probably better to leave the chains out. Though I think it would be fun to model the chains with a physics modifier etc. just for practice
but that's another thing
btw Kovanaama the scale of the chains is off, they're too small
Another thing, could it be possible to apply the same physics code that the antennas use to other objects in BF2? I'm not saying it would be practical, just wondering whether it's possible or has been done already. That way you could have the chains sway with the movement of the vehicle, in theory at least
