/* Spike -- THIS IS A HUGE CLUSTERFUCK.
the mins/maxs sizes of models in vanilla was always set to xyz -16/+16.
which causes issues with clientside culling.
many engines fixed that, but not here.
which means that setmodel-without-setsize is now fucked.
the qc will usually do a setsize after setmodel anyway, so applying that fix here will do nothing.
you'd need to apply the serverside version of the cull fix in SV_LinkEdict instead, which is where the pvs is calculated.
tracebox is limited to specific hull sizes. the traces are biased such that they're aligned to the mins point of the box, rather than the center of the trace.
so vanilla's '-16 -16 -16'/'16 16 16' is wrong for Z (which is usually corrected for with gravity anyway), but X+Y will be correctly aligned for the resulting hull.
but traceboxes using models with -12 or -20 or whatever will be biased/offcenter in the X+Y axis (as well as Z, but that's still mostly unimportant)
deciding whether to replicate the vanilla behaviour based upon model type sucks.
vanilla:
brush - always the models size
mdl - always [-16, -16, -16], [16, 16, 16]
quakespasm:
brush - always the models size
mdl - always the models size
quakeworld:
*.bsp - always the models size (matched by extension rather than type)
other - model isn't even loaded, setmodel does not do setsize at all.
fte default (with nq mod):
*.bsp (or sv_gameplayfix_setmodelrealbox) - always the models size (matched by extension rather than type)
other - always [-16, -16, -16], [16, 16, 16]
fte's behaviour means:
a) dedicated servers don't have to bother loading non-mdls.
b) nq mods still work fine, where extensions are adhered to in the original qc.
c) when replacement models are used for bsp models, things still work without them reverting to +/- 16.

//johnfitz -- correct physics cullboxes for bmodels
/* Spike -- THIS IS A HUGE CLUSTERFUCK.
the mins/maxs sizes of models in vanilla was always set to xyz -16/+16.
which causes issues with clientside culling.
many engines fixed that, but not here.
which means that setmodel-without-setsize is now fucked.
the qc will usually do a setsize after setmodel anyway, so applying that fix here will do nothing.
you'd need to apply the serverside version of the cull fix in SV_LinkEdict instead, which is where the pvs is calculated.
tracebox is limited to specific hull sizes. the traces are biased such that they're aligned to the mins point of the box, rather than the center of the trace.
so vanilla's '-16 -16 -16'/'16 16 16' is wrong for Z (which is usually corrected for with gravity anyway), but X+Y will be correctly aligned for the resulting hull.
but traceboxes using models with -12 or -20 or whatever will be biased/offcenter in the X+Y axis (as well as Z, but that's still mostly unimportant)
deciding whether to replicate the vanilla behaviour based upon model type sucks.
vanilla:
brush - always the models size
mdl - always [-16, -16, -16], [16, 16, 16]
quakespasm:
brush - always the models size
mdl - always the models size
quakeworld:
*.bsp - always the models size (matched by extension rather than type)
other - model isn't even loaded, setmodel does not do setsize at all.
fte default (with nq mod):
*.bsp (or sv_gameplayfix_setmodelrealbox) - always the models size (matched by extension rather than type)
other - always [-16, -16, -16], [16, 16, 16]
fte's behaviour means:
a) dedicated servers don't have to bother loading non-mdls.
b) nq mods still work fine, where extensions are adhered to in the original qc.
c) when replacement models are used for bsp models, things still work without them reverting to +/- 16.
