Modifying Texture Resolution research [UNSOLVED]

I've been trying to figure out how to alter the resolutions of textures but I've hit a road block in my research as I'm rather inept when it comes to hex editing. So, I will just share what I've got so far and hopefully it'll aid someone in solving the puzzle. I am using a floor file as an example.

Near the beginning of the floor file where all the dxt hex values are located you have to double the values to get double the resolution.


In the image above the value is already doubled from 00020002 to 00040004 so it also doubles the resolution from 512 to 1024.

So in the 2kxmodtool it looks like this:


As you can see the image size able to be imported has doubled to 1024 but this is where the other problem begins:


I think because the images are so large, they are leaking into each other's space within the file but I can't be sure.

you hit it on the head, the image "leaks" into the rest of the file. What Ariel has been doing with the HD court textures is changing all the spacing between each of the textures and models in the iff file. So he creates the space needed by changing the offsets of the other files. That is our roadblock.

Unfortunately, doing this to the logo.iff files, which only contain 1 texture so no need to worry about "leaking", can really screw up the textures in game too.
