Good.... Reading Valves (very intersting) stuff and some of the posts, I seem to have to restrict myself drastically in damagemodels.
In first place, it was the general technical side of "how did they do that", what had interested me.
And it gave very interesting insights.
And once again it proves, that the simple looking, rather unspectacular effects are the most hardest to achieve.

Now to my desingn-decision (I have not started a project):
Dismemberment\destruction would not be essential or important part of the game.
This would be more or less just eyecandy.
There seem just two possible ways, that I could implement.
But which one should I choose?
This is important, so that I know how to build up my models from the start up.

1. The Turok 2 Way. Attached Limbs on center-entity.
or
2. Create all the different damaged variants of the model and
interchange them based on the areas hit.

I want to use Bones-animation and Ent_Decal. But I suppose that ent_decal will not work with solution #2.
Because I think, when I change the model, the applieed decals disappears together with the exchanged model.
