First of all i would like to apologize for using the word idiot in my previous post. I just looked over it again and i must have been grumpy or something, I don't mean to insult new members to the c++ language.
Now that that's out of the way, yes you may be right corn. I was just trying to point out it's not a TextureType as people above have stated. I wanted to help you guys understand that the significance of the 0x4F4 is that it's the size of one member of an array. There are 64 members which is why 64 is included in your loop and the whole size of the member or struct is 0x4F4, within that 0x4F4 in each index of the loop there are 3 values that need to be set to a certain value in order to enable you to shoot through the wall.
