RE crashing when shooting: It appears that the render is having issues allocating models. Certain weapons are invisible in my hands on your map, grenades don't explode, and so on. The log is spammed with: RE_RegisterModel: R_AllocModel() failed for 'models/fx/grenexp_base.tik' messages.
Looking at the renderer code in opm, it could be due to the MAX_MOD_KNOWN limit being reached in R_AllocModel function:
Code:
if(tr.numModels == MAX_MOD_KNOWN)
{
return NULL;
}
Not
entirely sure why, but the size and complexity of the map likely has something to do with it. Though it could also be an isolated section (or sections) of the map that needs finding and fixing.
