Wrong section & the visible bug with models can be fixed like this.
then find Something simular this code below., you need to replace ur current one with the one under.
Code:
public Model(int modelId) {
byte[] is = aClass21Array1661[modelId].aByteArray368;
if (is[is.length - 1] == -1 && is[is.length - 2] == -1)
read622Model(is, modelId);
else
readOldModel(modelId);
if (newmodel[modelId]) {
scale2(4);// 2 is too big -- 3 is almost right
if(anIntArray1638 != null) {
for(int j = 0; j < anIntArray1638.length; j++)
anIntArray1638[j] = 10;
}
}
}
