WRC7 .PTX textures

[RiccoChicco]

Hi!

I try to edit some textures from the last WRC game, unfortunately once I extracted archives, I find a lot of .PTX textures. I'm quite conviced it's some sort of .DDS since it mentions DXT1/3/5 when reading it with an hex editor. I saw that someone else already asked something similar for WRC6, unfortnately no one answered.

If anyone know how to go to/from PTX to a more standard format, it will be greatly appreciated!

An example texture has been joined to the post

Normal un-compressed/un-obfuscated DXT3/5 file with MipMaps (Big endian!). See attachement

This file has modified/damaged DDS format, but you'll be fine if you read it after normal DDS header size. Anyway, just grab sample DXT1 DDS file and rebuild header.

its not big-endian or modified/damaged, just typical dxt stored in RIFF container with a 130 byte header.
seems the data might be stored in max chunk size of 0x80000, though before i make a script i need more
variety of samples to look at for compare. i plan on making a script to work with both WRC6 and WRC7.

Every day I learn something new, I though RIFF is only audio file. Thanks!

Wow! Great news! Thanks a lot!

if you upload more samples i will make a Noesis python script

edit
my WRC 6 ptx Noesis python script here seems to work with this game samples.
