The problem with black mesa it always return visible regardless where players are on the map ! (player is very far away and behind big stones/walls etc)

SM (1.11 - build 6520) and metamod (1.11 - build 1130)

@asherkin its a game data update missing but found nothing strange.

SDK update ? some one can check if its a SM issue or a game issue please ? @dvander @psychonic

thanks @psychonic for digging the issue with me,

After investigation together:

try replacing <sdk>/public/cmodel.h with the one from the csgo branch of the SDK
some of the other changes they have to IEngineTrace are from the CS:GO branch. I suspect they may have the Ray_t changes as well
without the extra member in it, the engine could be reading past the end of the struct we are passing to it

this works, tested on trace ray(ex) and tracehull(ex) with filter too
