Xenoblade Chronicles 2 texture format research

Been working with Ploaj (from TMR) on getting the model data and texture data put together, but sadly, we can't seem to find the texture size and texture type for each texture at all, which is making things a bit harder to finish.

I'll be including Rex (at least I hope it's Rex) up for ya guys to look at. As far as I know, the wismt file is a container with 2 directories, and then the files that's in those directories are all zlibbed, but after decompressing everything, the textures say nothing about texture size or texture type, it's just pixel data for them all, and we're both stumped on where the actual data is located at, so any help is appreciated!

Here's the files to Rex (or whoever it is, im sure it's rex tho since bl000101 is Pyra)

files:
arc - bone tree and structure
wiefp - effect something... most likely effect position bones?
wimdo - polygon data (as far as I know, it contains polygons and material data for the model)
wismt - model + texture container (zlibbed files inside it)


The Research
I used offzip to extract decompressed files from pc000101.wismt.

LBIM is the string to search for. They have the texture length and width, as well as format info. The info is before the LBIM magic.

I found them in 000007c0.czd and 000eb420.dc5.

Only have one sample though. Hoping for Nia(both) and weapons. <3

000007c0.czd also has shaders, with NVSD magic.

Some Rex mentions.
