collision model in hl2 - what are the limits ?

it's a rather simple question, i guess.

so i have this giant railing model with like 20 pillars on each side. now i did a simple collision model (2 boxes for each side) then the guy i made the model for said the model needs to have a hitbox around every pillar, so people can shoot through ingame.

since i have no idea at all about how the models in hl2 are handeled, displayed......i googled a bit and just found a wiki entry that said if a model has more than 16 (or 24 - it said with a special command it can be 24) then the hitbox parts are truncated (i guess that means "deleted").

so i just wanted to ask you guys, if that number could be true ?

and i think that if i had 60 hitbox parts in just one model that would be quite performance intensive, but like i said, since i have no idea at all, maybe its all fine to have 60 or more parts as a hitbox - but i just can't imagine, that that's alright.

i really hope you guys can help me on this

ah, exactly the kind of answer i needed

so such a nodraw brush blocks bullets, basically ?

great, thanks a lot twiz and insta

alright, told him everything you guys said and send him the smd's with the very simple collision model consisting of 4 boxes, just like had it in mind originally

this job done, next model to come
