Of all the 'niggling' damge model issues, this one is my greatest irritation :(

[retrojet]

Well if that screenie is cod, then my point will be mute...
What I was going to say is, that every DM feature must be quite a resource hit, so drawing a straight line may be an unfortunate compromise...
And a repeated jagged tear the same...

But however it is handled, somebody will perceive it as unrealistic and then we're back to square uno...

Before you ask... no, I don't have the foggiest idea how to code!
