Some Code I wrote Eons Ago (Part of getCVehicleInfo I beleiv

struct hashFindData {
    unsigned int dataHash;
    unsigned int calculationData;
    hashFindData *next;
};

hashFindData *getHashAddress(unsigned int hash) {
    short div = *(short*)(0x1EA3A7C+0x14);
    unsigned int v1 = hash/div;
    unsigned int v2 = v1*div;
    unsigned int dif = hash-v2;
    unsigned int add = dif << 2;
    unsigned int structAddr = *(unsigned int*)(   *(int*)(0x1EA3A7C+0x10)  +add);
    hashFindData *dat = (hashFindData *)structAddr;
}

unsigned int getCalculationData(unsigned int hash) {
    hashFindData *d = getHashAddress(hash);
    while (d != 0) {
        if (d->dataHash == hash) {
            return calculationData;
        }
        d = d->next;
    }
    return 0;
}

int main()
{
    //so essentially, if this = 0, the model is loadable and spawnable
    //if it returns 0, then u gotta teleport to the option to get the game to load it into this data first so this doesn't return 0 anymore
    getCalculationData(some hash);
}
