Hi everyone,

I'm trying to make a texture mod Batman Blackgate, but I'm stuck on the game's TXTR texture format.

I'm not a programmer, so I've mostly been learning as I go with some help from AI. I managed to extract the .ara archives using QuickBMS, but I can't figure out how to decode the TXTR files or get them to open in Noesis.

I know this is a pretty niche game, but I don't want to give up on the project. If anyone has experience with reverse engineering game texture formats or writing Noesis plugins, I'd really appreciate any advice.

batmanstxtr.zip dec.py archives 1- 17kb.zip game files and bms.zip

from inc_noesis import *

import rapi
import os

def registerNoesisTypes():
   handle = noesis.register("Batman: Arkham Origins Blackgate - Texture", ".txt")
   noesis.setHandlerTypeCheck(handle, noepyCheckType)
   noesis.setHandlerLoadRGBA(handle, noepyLoadRGBA)
   noesis.logPopup()
   return 1
        
def noepyCheckType(data):
   bs = NoeBitStream(data)
   if len(data) < 20:
      return 0
   return 1
   
def noepyLoadRGBA(data, texList):
    bs = NoeBitStream(data, NOE_BIGENDIAN)
    BaseName = rapi.getExtensionlessName(rapi.getLocalFileName(rapi.getInputName()))
    cPos = bs.tell()
    bs.read(8)
    TextureSizeOffset = bs.readUInt()
    TextureWidth = bs.readUShort()
    TextureHeight = bs.readUShort()
    bs.read(4)
    PixelFormat = bs.readUShort()

    bs.seek(TextureSizeOffset, NOESEEK_ABS)
    TextureSize = bs.readUInt()
    data = bs.read(TextureSize)

    if PixelFormat == 6:
        texFmt = noesis.NOESISTEX_DXT1
        print("Pixel Format > DXT1 >", PixelFormat)
        
    elif PixelFormat == 8:
        texFmt = noesis.NOESISTEX_DXT5
        print("Pixel Format > DXT5 >", PixelFormat)
    else:
        print("Unknown Pixel Format > ", PixelFormat)
            
    texList.append(NoeTexture(rapi.getInputName(), TextureWidth, TextureHeight, data, texFmt))
    return 1

But need more samples to confirm PixelFormat.
