To sound like the Bionic Man... Why the hell are we wasting time having modders do this when we can demand the devs do it?!? It's never gonna be as cool if they don't!
Just kidding. Love those graphics. Play with debris and just about everything I can get my hands on. Woot!
Well, devs can make more that modders...
Now, custom debris use .mesh... .mesh who have a harcoded limit of 800... original game already using over 400 of them...
Big mod like 7DS are already hitting these limit, mod using rotating piece for model use double the usual .mesh ... as now, i am working on a animated model, only 1.5k tri but need a little over 10 .mesh ...
So, as for debris, in place of add some .mesh who will make us hit the hardcoded .mesh limit more fast... best is to implement something like physx in the next sins release...
For example, the game mafia... top with physx enabled :

Can be used for ship debris, for destroy planet who become asteroid field, for make hole/damage on ship who are hit, etc... all this without adding numerous .mesh who limit the modders in their work...
In the same time, why not add basic skeleton... while allow moving piece, moving turret with firing arc embeded in the skeleton join limit, and more...
Well, i don't ask it for rebellion since rebellion is based on the 2007-2008 iron engine... but in case of a iron II engine for a Sins II, there is plenty of news possibility who exist today... and since all this ask GPU power and that a lot of people have very good graphic card, why no use these power...
